My mother was a Willison, but her mother was born a Dickson. The details below are largely based upon the Dickson family Bible, Sir John Johnson's Orderly Book, O'Neill ancestral pedigrees, and The Genealogy of the Royal Family O'Neill. Those data have naturally led to further discoveries via other family sites. I have included a Dickson family Bible extract Sir William Johnson's descendent line into the Dickson and Willison families. The nemes shown have been entered into the family database.

The Dickson Family Bible

Bibles have long been a source for family records and the Dicksons rose to some prominence in Canada in politics, law, Indian Affairs, and in the War of 1812: they are shown below. Near the bottom of the second page someone has recorded the link to the Johnson family and William, the Mowhaw Baronet. The two families are related through Anne, Sir William's daughter. She married Christian Daniel Claus, who worked with her father, Sir William, in supervising the northern Indians. Eventually their great-granddaughter married Walter Dickson, from whom my grandmother descended.



The following is from a modern source who has obtained a copyright to the original military log by Sir John.[1] The log, or more accurately a record of his military orders and significant events, was maintained throughout the Revolutionary period. It is quoted verbatum below as a matter of family history, since it included John's family pedigrees. William Johnson was John's father and William was well aware of his family background and his descent from the Irish kings, which are shown above. The family members identified below migrated to Canada via Kingston and Montreal, and from there to England. Many stayed in Canada. Further sources are shown in the database.

"Boldness Wins."
(Original motto of Sir WILLIAM JOHNSON, Bart.)

"I cannot see," observes a gentleman (of New York Whig antecedents and ancestry), at once an historical scholar, a practical soldier and an accomplished man of business, "how a man so formed and trusted in himself and his family [as Sir John Johnson] could have acted differently than he did."

In many respects the two greatest men who administered the affairs of the colony or province, or, even since, of the State of New York, were Lieutenant-Governor, acting Governor, James de Lancey, and Sir William Johnson, Bart., the "Indian Tamer"-the Conqueror at Lake George in 1755, and the Capturer of Niagara in 1759. If space permitted, it would be a very interesting and agreeable task or duty to clear up some historic doubts in regard to the first Sir William and introduce illustrations of his ability which have never been presented to the American public.

* The following genealogy of the Johnson family is compiled from various sources : from memoranda furnished by the present Baronet, Sir William George Johnson, from Burke's "Peerage and Baronetage of Great Britain, from Sabine's "Loyalists of the American Revolution," from Wm. L. Stone's "Life of Sir William Johnson, Bart.," &c., &c.

* It has been bruited that originally the family name was not Johnson, but Jansen, and that the first who bore it and settled in Ireland was a Hollander, who, like many of his countrymen, went over afterwards with William III in 1690, won lands and established themselves. If this report had a grain of truth in it, that the name should become anglicized immediately would be nothing remarkable, since hundreds of similar and of far greater transmutations and travesties, some amounting to simple absolute translations, occurred in this State within a generation after its settlement: the Feuersteins becoming Flints, the Muhlers Millers, &c., &c. This Jansen story, however, is a myth, like many of the stupidities which are engendered by ignorance or started through envy or other like meannesses in illiterate neighborhoods. Col. Guy Johnson, nephew of Sir William, always retained a touch of the brogue. "His tongue bore evidence of his Irish extraction" (Captain Snyder, in Stone's "Brant," II. 67.)

It is marvelous what ridiculous nonsense has been published in regard to the antecedents and adventures of this remarkable man. The following is the literal truth, furnished from a most authentic source:

"The Hon. Sir William Johnson, Bart., in America, was the son of Christopher Johnson, Esq., of Smith-Town, County Meath (Ireland), a gentleman of great repute and renown, descended from a distinguished Irish family,* and of Anne Warren, daughter of Michael Warren, Esq., of the same county, and sister of Sir Peter Warren, Kt, Knight of the most Honorable Order of the Bath, Vice-Admiral in the British Navy under George II (and well-known for his exploits-among these his cooperation with Sir William Pepperell in the famous expedition against Louisbourg, the French Gibraltar in America, in 1745), and niece of Admiral Lord Aylmer, of Balrath, County Meath, Ireland. Shane O'Néill

"The above Christopher Johnson was son of William Johnson, then called MacSean or MacShane, a "general of very great repute and credit in that part of Ireland (county Meath, whose principal river is the Boyne, famous for the victory of William III. over James II., 1st July, 1690), and of Anne Fitzsimmons of Tallynally, county of Westmeath. William MacSean was the son of Thomas MacShane and Frances Fay, of the very ancient family of Derrinaganale, county Westmeath. This Thomas MacShane was son of John (O'Neil), from whom the MacSeans of that family were called, and was descended from the Royal (Irish) family of Dungannon, County Tyrone, formerly princes of Ulster and monarchs of Ireland, "antecedent to Christianity" and "before the coming of St. Patricke." The family of Warren (here referred to), of Warrentown, is the head and stock of several illustrious families of that name in Ireland, and the founder was one of the principal followers of Earl Strongbow when he conquered Ireland, 1169-70. This family of Warren is descended in a direct legal line from the Marquises of Warrene, in Normandy, France.

According to Sir William George Johnson, 4 Bart, there is an exceptional honor attached to the patent of nobility conferred upon the first Sir William and his son, Sir John, which is almost unprecedented in British history. The patent which perpetuates the baronetcy in this family contains a clause which gives the title of "Knight" or "Sir" to the eldest son on his attaining his majority, an extraordinary clause, as knighthood as a rule is not hereditary, but is conferred for special services and terminates with the life of the recipient.

I. WILLIAM JOHNSON, Esq. (afterwards Knight and Baronet), was born at Smith Town, County Meath, Ireland, and subsequently adopted by his maternal uncle, Admiral Sir Peter Warren, K. B., capturer of Louisbourg, &c., and went out with him to North America, where he rose to the rank of Colonel in the British Army, Major-General of the Provincial Forces and (or) of the Militia, 16th April, 1783, and distinguished himself as a military commander during the French (American) War (1754-63), and as a negotiator with Indian tribes. He was created a Baronet 27th Nov., 1755. In 1756 he received his commission as "Colonel, Agent and Sole Superintendent of all the affairs of the Six Nations and other Northern Indians," "with no subordination but to London." He died 11th July, 1774, of chronic malignant dysentery, aged 59, at his seat, Johnson Hall, Tryon County, New York, leaving
by Catherine Weisenberg [Weissenberg ?], his wife:

I.. JOHN, his heir.

II. ANNE, married to Col. DANIEL CLAUSS, of North America, and died about 1798.

III. MARY, married to Col. GUY JOHNSON, and had two daughters: 1. Mary, wife of Field Marshal Lord Clyde, queller of the East India Mutiny, originally known as Sir Colin Campbell, and mother of Gen. Sir Guy Campbell ; 2. Julia.

The son and heir of Sir William George Johnson, Bart.:

II. SIR JOHN, of Johnson Hall,* Tryon (afterwards Fulton) County, N. Y., finally of Mount Johnson, Montréal: Colonel of Regiment of Horse in the Northern District of New York, in 1773; Major-General of the Militia belonging to the same portion of the Province after the decease of his father; Lieut.-Col. commanding the Loyal or Provincial " King's Royal Regiment of New York," otherwise "The Queen's Loyal New Yorkers;" or "Johnson's or Queen's Royal Greens;" Colonel, B. A., 21st October, 1782; Brigadier-General of the Provincial Troops, &c., 14th March, 1782; Superintendent-General and Inspector-General, General of the Six Nations of Indians and their Confederates, of all the Indians inhabiting Our province of Québec and the Frontier, 16th September, 1791 (a copy of Sir John's commission is appended as a note); * Colonel-in-Chief of the six Battalions of the Militia of the Eastern Townships of Lower Canada. He was Knighted at St. James', London, 22d Nov.,

* To furnish some idea of the condition of insecurity in which the Johnson family lived, and the state of preparation maintained at the Hall-the family home-a semi-fortification, the following order, copied from the original by Col. T. Bailey Myers, is inserted entire.

It was by a father who was so careful in his instruction, who was so capable in the handling of men, so conscientious in his labors, administrative, executive and military, and so fortunate in his enterprises, Sir John Johnson was brought up and prepared for the arduous career which absorbed the best portion of his active life.

"1st. You will keep your Party sober and in good order and prevent their having any unnecessary Intercourse with the Indians least any difference might arise between them from too much familiarity.

2d. If any difference should arise between them, if the Indians use any of your party ill, I am to be immediately acquainted with it.

3d. The Sergeant to take care that the Men's Quarters be kept very Clean and that they wash well and freshen their Salt Provisions, the neglect of which makes them subject to many Disorders.

4th. You will in the day time keep one Sentry on the Eminence to the Northward of the House, who upon seeing the enemy advance is to fire his piece and retreat to the Fort. Another Sentry to be posted at the Gate of the Fort on the outside, who is also to enter the Fort on the advanced Sentry alarming him.

5th. When there are no Indians here the Gates to be locked at 8 o'clock in ye Evening and opened at Six in the Morning, first looking around about to see that all is safe and clear, the advanced Sentry then to be posted Every Day.

6th. Whenever an alarm is given by the advanced Sentry, you will order three Patteroes [or Peaeroes, a very small kind of cannon] immediately to be fired, that being the signal I have given to the Mohawks, and on their approach near the Fort, when challenged, they are to answer "George" as distinct as they can, then to be admitted if practicable.

7th. In case of an attack the 3 Bastions to be properly manned and the 2 curtains also, there mixing some of my People with yours. The remainder of my People to man the Dwelling House and fight from thence, making Use of the Four Wall Pieces and Musquetoons and of the windows fitted for them.

The men's arms and ammunition to be kept in Good Order.
Lieut. August the 9th, 1756. Yrs.,

NOTE.- Cause of this absence. On the 10th of August the Marquis de Montcalm, who had succeeded Baron Dieskau his command of French army, invested Oswego. On the 13th of this the garrison, Shirley and Pepperell's regiments, 1600 men, evacuated and retreated to the old fort across the river, and surrendered on 13th, and both forts leveled. Johnson was at Albany on the 20th when the news arrived, and was sent by Ld. Loudoun with two battalions of militia to German Flats to support Gen. Webb, who had started from Albany for the relief of the garrison two days before the surrender, but, on receiving intelligence of it, retreated with precipitancy to German Flats, which ended Loudoun's campaign and disappointed and incensed the Six Nations, who looked for his protection, and gave Sir William much trouble ; the Mohawks only remaining reliable, the others for a time negotiating for peace with the French.

GEN'L J. W. DE PEYSTER, BUFFALO, March 80, 1882.

DEAR SIR:- I enclose copy of Sir John Johnson's commission as Superintendent-General of Indian Affairs. The original is bound up in a collection of autographs and documents in my possession, and could not be detached without mutilation.

Possibly this may be of some slight service to you.

Very respectfully yours, WM. C. BRYANT.

1765. (On the death of his father, Sir William (I.), Sir John positively refused to accept the succession to the former's dignities and offices in connection with the Indians, and they were conferred upon his cousin. Guy Johnson, who exercised them throughout the Revolutionary War, and thus Sir John and Col. Guy have often been confounded, to the disadvantage of Sir John. Sabine says, "Col. Guy Johnson's intemperate zeal for his royal master caused the first affray in that [Tryon] county."

Given at Our Court at St. James's, the Sixteenth day of September, 1791, In the Thirty First Year of Our Reign.

By His Majesty's Command,


ARMS.-Argent, two lions counter-rampant, supporting a dexter hand gules; in chief, three estoilles of the last, and in bas, a salmon naiant in water, proper.

MOTTO, -"Nec aspera terrent." "Difficulties do not stop (or deter) or dismay." " BOLDNESS WINS."

Sir John Johnson, might have exclaimed, in the words of Dryden:

" Fortune came smiling to my youth, and woo'd it,
And purpl'd greatness met my ripen'd years,
When first I came to empire, I was borne,
On tides of people crowding to my triumph:
The wish of nations, and the willing world
Receiv'd me as its pledge of future peace.
I was so great, so happy, so belov'd,
Fate could not ruin me, 'til I took pains,
And work'd against my fortune; chid her from me,
And turn'd her loose, yet still she came again.
My careless days, and my luxurious nights,
At length have wearied her ; and now she's gone.
* * * * * *
Oh ! I am now so sunk from what I was,
Thou find'st me at my low-water mark:

The rivers that ran in, and rais'd my fortunes,
Are all dried up, or take another course.
What I have left is from my native spring;
I've still a heart that swells in scorn of fate."

O'Neill Ancestral Pedigree Sources

The O'Neill family provided Ireland kings for centuries and the Irish kings are well documented with credible reliability back to 300-400 AD.[2] There is an additional millenium of pedigree stretching backing further, however, some might question the reliability of that data. The records were kept by memory and perhaps surprisingly many of those records appear to be supported by the scant archeological and other evidence available.[3] The Irish spoke Gaelic - despite the civilising attempts of Englishmen - and John is written as Sean, or Shane, in Ireland. There are specific links to the colonial Johnsons.[4]

Johnson Origins

William George Johnson, Mohawk Baronet, Major General, Superintendent of Northern Indian Department, born 1715, died 1774
Created baronet in November 1755. Called 'Warraciyagey' by the Indians in the New York Colony. He held a regular army commission as a colonel and a colonial commission as a major general. He was appointed Indian agent and Superintendent General of Northern Indian Affairs in 1744. In 1755 he directed the military operation at Crown Point to stop a French invasion under Baron Ludwig A. Dieskau, and fought and won the Battle of Lake George in September and captured Fort Niagara in 1759. He founded Roger's Rangers and Columbia University; and was loved by the Indians with whom he was always fair. He never married, but had two particular 'wives' Catherine Weisenberg (from whom we descend) who he called wife, and the Indian Princess, Molly Brant. He fathered over 700 children!
Christopher Johnson, born 1679, died c1730.
A gentleman farmer in Ireland. He married Anne, the sister of Vice Admiral Sir Peter Warren, and the daughter of Michael Warren of Warrenstown, County Meath.
William Johnson, Major General, born c1650
This William Johnson, was first called MacSean or MacShane, a "general of very great repute and credit in that part of Ireland (county Meath, whose principal river is the Boyne, famous for the victory of William III over James II, 1st July, 1690). William then also took the anglicised name Johnson. An Irishman who lived on English money in the post-civil war era would require a demonstration of loyalty - like an English name.
Thomas MacShane, born c1625
Thomas adopted the surname MacShane = son of Shane (O'Neill). Thomas married Frances, daughter of Thomas Fay of Derrynagare, Westmeath. After having been banished to Mayo by Cromwell, Thomas anglicized his name to Johnson to mollify the large English presence in the area. Thomas was of the very ancient family of Derrinaganale, county Westmeath.
Shane O'Neil, born c1600
Son of Sir Turlough, Lord of the Fews (born c1600)
Turlough O'Neill, Lord of the Fews, born c1560
Lord of the Fews. Married Sara, daughter of Sir Terence (Turlough "Leynagh"), The O'Neill Mor (1567 - 1593). He died 23 February 1639. (The Fews are defined as a small geographical area in Armagh. The Fews (Lower and Upper) were one and then two baronies in Ulster. The O'Neill of the Fews were later overlords in this ancient Oriel (Armagh) territory. The Fews were a great forest south of Dungannon, conquered and occupied by by Aodh O'Neill in c1508. Sir Turlough gained a pardon from Queen Elizabeth I of England for his rebellion, which cleared his entire clan via the first local census in 1602.)
Henry O'Neill, Lord of the Fews, born c1525
Henry was living in 1563 and was at war with King Shane "the Proud". Henry married the widow of Ferdorcha (Matthew) O'Neill, 1st Baron of Dungannon, parents of Aedh Ruadh (Hugh "the Red") last King of Ulster and 1st Earl of Tyrone. (The English had tried to break O'Neill power by offering the kingship of Ulster to Ferdorcha, a bastard son of King Conn Bacach. This upset the senior legitimate son - Sean/Shane - who seized the crown and defied the English.)
Feidhlimidh Ruadh O'Neill, Lord of the Fews, born c1501
Felix "the Red", Lord of the Fews. Feidhlimidh supported Niall Conallach O'Neill as Tanist of Tyrone (1531). He brought thirty horsemen to support Marshal Bagenal against Sean "the Proud" (see Sean above), in 1551, but was defeated by Sean who slew fifty of his allies in 1554. (A tanist was the heir-apparent to a Celtic chief, elected from amongst the chief's family during his lifetime. This process was used in Ireland, Dalriada, and Scotland - the latter to 1034.)
Art O'Neill, King of Ulster, born c1470
The O'Neills were the hereditary kings of Ulster. Art was the senior heir of The Fews clan when the main (Ua Niáll) O'Neill line died out.
Aedh O'Neill of the Fews, Tanist of Cenel Eoghain, born c1417
Tanist of Cenel Eoghain and ascendant of the lineage of The O'Neills of the Fews. Aedh (Hugh) wounded Brian O'Neill in single combat on horseback (1435) and died in 1475. (A tanist was the heir apparent to an ancient Celtic chief, elected during the chief's lifetime.)
Eoghan O'Neill, King of Ulster, born c1391
Eoghan was King of Ulster 1432 - 1455 AD. Crowned on the flagstone of the kings at Tulach Og (Tullahogue). He was opposed by Brian, grandson of Henry "the Confused". Eoghan (Owen) captured Brian and two of his sons and mutilated all three by cutting off one hand and one foot from each in 1435. Eoghan resigned the throne to his son in 1455 and died in 1456. He married Catairona (Catherine), daughter of Ardgal MacMahon, King of Oriel (1402 - 1416).
Neil Og O'Neill, King of Ulster, born c1337
Neil Og was King of Ulster 1394 - 1403 AD. Styled Ua Niáll Mor (The Great O'Neill) a title still in use today to distinguish this branch Clan Chief from their rivals the senior or Clannaboy Chief who is styled Ua Niáll Buidhe (The O'Neill Buidhe). Niall was knighted in Dublin by King Richard II of England in 1394. He died in 1403. He had married Una, daughter of Domnall O'Neill.
Niall Mor O'Neill, King of Ulster, born c1316
The Great Red Hugh O'Neill - The O'Neill Mor - Chief of his name, was inaugurated Chief of his Clan - the last Chief of the royal O'Neill clan to be formally inaugurated; according to the ancient traditions of his ancestors.
Aedh Baemhar O'Neill, King of Ulster, c1271
King of Ulster 1344 - 1364 AD. Deposed his kinsman King Henry O'Neill (head of the senior or Clannaboy branch) in 1344 and invaded Clannaboy itself in 1345 but was defeated. Aedh is known to have levied tribute from the settlers in Louth. His seal bears the inscription "S. Odonis O Neill Regis Hybernicorum Ultonie" and a shield with the famous Red Hand of Ulster, the original O'Neill arms. He married Gormfhlaith, possibly the daughter of Aedh O'Donnell, King of Tirconaill. He died in 1353 AD.
Domnall O'Neill, King of Ulster, born c1245
King of Ulster 1283 - 1286 & 1295 - 1325 AD, Royal Heir of Ireland. He was deposed by the (the English) Red Earl of Ulster in 1286 but restored in 1295. He had sent aid to King Robert Bruce against the English in Scotland. Domnall renounced his own right to the Irish High Kingship in favour of King Edward Bruce, to save Ireland (1316 AD). Headed the Remonstrance to Pope John XXII (1325 AD) as "Donaldus Oneill Rex Ultoniae, true heir by hereditary right of all Ireland". Fought for Edward Bruce at the fatal Battle of Dundalk in 1318. He died in 1325 AD.
Brian Cathan an Duin O'Neill, King of Ireland, born c1199
The last High King of Ireland , 1258 - 1260 AD (after Roleric or Rory O'Connor, son of Toirdelbach or Turlough O'Connor). This is important because most references do not list Brian O'Neill as the last of the Irish High Kings as Britain's King was recognised as the King of Ireland. Some list him as the self-styled King of Irish Kings. However, Brian was acknowledged by his peers (O'Connor of Connaught, O'Melaghlin of Meath and O'Brien of Thormond) in 1258 AD, who willingly gave the requisite "hostages", binding their acceptance of him as High King of Ireland. He smashed the rival Macloughlinn branch, killing his predecessor King Domnall MacLochlinn and ten of his family, establishing O'Neill supremacy in the north for up to four more centuries. He became King of Ulster in 1241 AD and formed the great Irish confederacy to drive out the English in 1256 prior to becoming Ard Ri ("High King"). Brian was killed in the Battle of Downpatrick (1260 AD) and his head was sent to London. He married Jill of Argyll, possibly the daughter of Duncan MacDugall, King in the Herbrides and Lord of Lorn.
