One of my sixth great grandfathers was a Scottish nobleman, James Duff, Earl Fife of Banffshire (1729–1809). He had at least three illegitimate children, my fifth great grandfather William Duff (1754–1795), his brother James, and a daughter called Jean.
James Duff acknowledged them as his own and all three received a good education at his expense.
William Duff was sent to the Royal Military Academy Woolwich in southeast London, a training college for officers of the Royal Artillery and Royal Engineers. On 11 December 1770, William graduated with a commission as Lieutenant in the 7th Royal Fusiliers.
On 15 April 1773, William Duff embarked with his regiment for Canada, the journey taking 11 weeks. He was still in Canada when the American Revolutionary War began in 1775.
When in that year American forces invaded Canada, most of Duff’s regiment was forced to surrender. He was taken prisoner in the capture of Fort Chambly by Rebels on 18 October, and though it was hoped that he might soon be returned in an exchange of prisoners he was not released until early 1777.
In May 1787 William and his new wife sailed for Quebec, where he was put in command of the regimental headquarters. In 1789 the regiment moved, first to Montreal, and then in 1790 to frontier posts along the Niagara River. In 1792 the regiment moved back to St. John’s (Fort Saint-Jean) in Quebec.
In 1790 Dorothy gave birth to their daughter Sophia Duff. She was my fourth great grandmother.
William Duff retired from the army in March 1793. On 5 July 1795 he died aged 41 at Fulford, near York.
One of my fifth great grandfathers was William Duff (1754–1795), the second natural son of James Duff, later Earl Fife of Banffshire (1729–1809).
William Duff was baptised on 16 March 1754 at Fordyce. His mother, Margaret Adam of Keith, was the personal maid of the Countess Fife, the mother of James Duff, that is, the mother of William’s father.
James Duff acknowledged William and his brother James and sister Jean as his children and all three received a good education at his expense. Care of the children was entrusted to William Rose, the factor (agent) of Lord Fife . The correspondence on this matter between William Rose, Lord Fife, and the three Duff children is extant, some being published in the 1925 book Lord Fife and his Factor.
William Duff was educated at the Royal Military Academy Woolwich in southeast London, a training college for commissioned officers of the Royal Artillery and Royal Engineers. There is a letter from William in 1770 when he was about 16 years old describing his course of studies:
Rise at 6 and go for a walk. Breakfast 7.30. Study from 8 to12. After dinner, military exercises. 3 to 6 study.
The book of the Duffs Volume 2 page 516
On 11 December 11 1770, William obtained a commission as Lieutenant in the 7th Royal Fusiliers, and in September 1771 he wrote from Chatham Barracks to his father at Duff House :
Since I wrote your Lordship last I have been detailed, with twenty men, for a week, to Upnor Castle, a place about four miles from here. This is a duty we take by turns. All this marching about of late has been very expensive to me, and within these two months (during which time I have never been settled in one place) it has cost me upwards of eighteen pounds. Our regiment, I believe, will remain as it is for the winter, but it is generally thought we shall march some other way before February next. My brother sets off for Scotland, with the first ship. I wanted to get to London, for a day or so, to see him before he went, but I really could not get leave. We are now so thin, that I have the Sash every other day almost. I understand your Lordship is killing the Deer just now, and I dare say you will have good diversion. I have just got another step in the Regt., so that there is now five under me.

Eighteen pounds in 1771 is probably equivalent to more than 30,000 pounds today. The website MeasuringWorth states to compare the value of a £18 0s 0d Commodity in 1771 there are four choices. In 2020 the relative:
real price of that commodity is £2,413.00
labour value of that commodity is £32,180.00
income value of that commodity is £35,310.00
economic share of that commodity is £273,500.00
On 15 April 1773, William Duff embarked with his regiment for Canada, the journey taking 11 weeks. He was still in Canada in 1775, when the American War of Independence broke out. He wrote to his brother, Sir James Duff of Kinstair, on 21 May 1775 from Quebec. The 7th Royal Fusiliers were stationed with the 26th Foot in Lower Canada; the two regiments were loosely scattered among frontier posts, and both were at very low strength, together mustering only seven hundred men.
At the time of the American invasion of Canada in 1775, most of the regiment was forced to surrender. The 80 man garrison of Fort Chambly, Quebec, attempted to resist a 400-man Rebel force but ultimately had to surrender in October 1775 and the regiment lost its first set of colours.
William Duff was taken prisoner by the Americans, probably at Fort Chambly in October 1775. Though it was hoped he might be returned in an exchange of prisoners, he was not released until early 1777.
In February 1777 he wrote to his father from Staten Island about the purchase of a company in the Regiment. William foreshadowed the expense stating “There is not a Company that has sold for less than Seventeen hundred pounds.” He asked his father to confirm that his father would purchase it for him and requesting security.
Seventeen hundred pounds in 1777 was probably equivalent to three million pounds today . From the website MeasuringWorth:
real price of that commodity is £224,600.00
labour value of that commodity is £2,858,000.00
income value of that commodity is £3,110,000.00
economic share of that commodity is £22,870,000.00
William left the 7th Regiment and was promoted to captain in the 26th Foot on 9 April 1777.
On 4 January 1786, William Duff now Captain of the 26th Regiment of Foot was promoted to Major; at the time he and the regiment were serving in Ireland.
On 9 April 1787 at Redmarshall, Durham, Major Duff of the 26th Regiment married Miss Skelly, of Yarm, daughter of the late Gordon Skelly Esq., Captain in the Navy. The book of the Duffs describes Dorothy as niece of Lord Adam Gordon, and the third Duke of Gordon; her grandmother Lady Betty Skelly (1717 – 1769) was sister to Cosmo, 3rd Duke of Gordon (1720 – 1752. Dorothy’s great uncle, Lord Adam Gordon (1726-1801) was colonel of the 26th Regiment of Foot from 1775 – 1782.
In May 1787 William wrote to William Rose from Cork :
We expect to sail to-morrow for Quebec. After various delays we reached this place a fortnight since. I am, as you often told me I should be, happier than ever in possession of a real, confidential friend. Everyone likes her. Were we richer it would be better.

The headquarters of the regiment in July 1787 at Quebec was under the command of Major William Duff. The regiment moved to Montreal in 1789, and then to the frontier posts along the Niagara River in 1790. It moved to St. John in 1792.
William took his wife Dorothy to Canada. They had one daughter, Sophia Henrietta, born about 1790. It seems likely she was born in Canada.
William Duff retired from the army in March 1793.
William Duff, major in the 26th foot, died on 5 July 1795 at Fulford near York. He has a memorial in the Duff House Mausoleum at Banff, Aberdeenshire, Scotland. The inscription reads:
Sacred to the memory of William Duff of the 26th Regiment, a meritorious officer, a most sincere friend, an affectionate husband, an indulgent parent. He lived esteemed and respected. He died regretted and lamented in the 41st year of his age in the year of the Lord 1795.

William’s daughter Sophia was about five years old when her father died. Sophia and her mother stayed in contact with William’s family.

Sophia Henrietta Duff, my fourth great grandmother, was born about 1790, probably in Canada, to Major William Duff of the 26th Foot and Dorothy Duff nee Skelly.
Shortly after their marriage William’s regiment was posted to Canada and Dorothy accompanied him there. William retired from the army in March 1793 and the family returned to Yorkshire.
Major William Duff died aged 41 on 5 July 1795 at Fulford, near York. He was survived by his widow and only child. His inscription in the Duff family mausoleum (at Duff House, Banff, Aberdeenshire, Scotland) stated:
Sacred to the memory of William Duff of the 26th Regiment, a meritorious officer, a most sincere friend, an affectionate husband, an indulgent parent. He lived esteemed and respected. He died regretted and lamented in the 41st year of his age in the year of the Lord 1795.

Dorothy and Sophia stayed in touch with William’s family. A letter written by Dorothy to her father-in-law in London mentions a visit to William’s sister, and that Sophia was visited at school by her paternal grandfather.
Dorothy Duff (William’s widow) to Earl Fife Richmond, Yorkshire Dec’r 23rd, 1801. My Lord,— I have to thank you for a letter which yu were so good as inclose me fr Lady Duff before you left Duff House, and after being so long without hearing fr your Lordship, was glad to have so good an account of you which was confirmed to me by ye Miss Whartons who wrote me after ye Ball you gave them and that they seemed to have much enjoyed. I have to thank you, my Lord, likewise for your visit to Sophia at Doncaster, where, she tells me, you were so kind as to call upon her notwithstanding a very bad day on which you walked up to ye School, and by which she was much flattered. I had ye pleasure of receiving her a few days ago in perfect health when I returned home after being near three months with my friends at Redmoss Hall. Sophie is wonderfully grown, and is now nearly as tall as I am. When she was with me in Summer I had her at Scarborough two months for ye sea bathing, which gave us an opportunity also of being wt Miss Duff who we had not seen for a very long time. She is by this time gone to Ly Norcliffe. I hope ye much wished for Peace will be ye means of bringing Sir James and Ly Duff soon to England. Your Lordship may perhaps have heard that my Brother is married. It took place here a week ago, before I came home, and he has entirely left ye army — in which he has relinquished very flattering prospects. Your Lordship would be sorry for ye death of poor Ld Adam Gordon — in whom I lose an affectionate relation and friend. I was deeply hurt at ye event- Sophia and I were to have spent this coming Christmas wt him at ye Burn. It was so settled when he was so kind as visit me here in ye summer, but our plans formed so long have proved vain. Sophia sends her duty to your Lordship.— Wh my respectful good wishes I remain, My Lord, your much obliged, etc., etc., D. Duff. The Earl of Fife, Fife House, London.

The letter mentions :
Sophia, who was about 11
William’s sister, Jean Duff,
William’s brother, Sir James Duff and his wife Basilia, Lady Duff nee Dawes
Dorothy’s brother, Gordon Skelly, who on 15 December 1801 married Elizabeth Newsome
Dorothy’s great uncle, Lord Adam Gordon, the brother of Dorothy’s paternal grandmother. He died on 13 August 1801.
Sophia’s school at Doncaster was probably the school of Mrs Ann Haugh on Hall Cross Hill, which opened in February 1797, accepting 12 young ladies. Mrs Haugh was the wife of the painter George Haugh, who taught his wife’s pupils.
Dorothy Duff nee Skelly, widow of Richmond, Yorkshire, remarried to Captain George Tobin of the Royal Navy on 13 June 1804 at St George, Bloomsbury, England. Her daughter Sophia was then about 14 years old.
Two children were born to Captain Tobin and Dorothy: George in 1807 and Eliza in 1810.

We each have two parents, four grandparents, eight great-grandparents, and so on; the numbers double with each generation. In ten generations we have 1024 great great … grandparents.
In twenty generations we would have 1,048,576 18th great grandparents. While this is possible in theory, it is more likely that we have far fewer, simply because our forebears married someone related to them. This is called ‘pedigree collapse’: we have fewer forebears, with multiple lines of descent from the same person.
Recently I have started to record more of my genealogy on Wikitree. I like the idea of collaborating with cousins on a single family tree. Wikitree strives for historical accuracy by requesting that facts are supported with citations. Collaboration means I can see my connections to forebears further back in time. Wikitree is free and contributors sign an honor code of shared of ethics and principles.
There are some interesting applications to help one analyse one’s family tree on Wikitree and one of these is “Ancestor Explorer” developed by Chase Ashley https://apps.wikitree.com/apps/ashley1950/ancestorexplorer/. The app allows you to see a sortable list of all ancestors of a particular person (Descendant) for up to 20 generations back. That list shows the number of lines to the same ancestor if there are multiple lines of descent; an indication of pedigree collapse.
The tool tells me that I have 3030 unique ancestors and 20,016 duplicate ancestors (additional lines of descent from a unique ancestor) within 20 generations. That is a lot of cousin marriages leading to a lot of duplicates.
It appears, for example, that I am descended in 1035 different ways from Marjorie Carrick (abt 1252 – 1292). By one line of descent she is my 19th great grandmother and by another line of descent she is my 30th great grandmother. As far as I can see, all the 1035 lines of descent are either through Helen (Kinnaird) Dana (abt 1746 – 1795), one of my fifth great grandmothers or through Sophia Henrietta (Duff) Mainwaring (abt. 1790 – 1824), one of my fourth great grandmothers on a totally different branch. Both women have long Scottish lines of descent that have been well documented on Wikitree.
My tree on Wikitree is by no means complete. I have recorded only 20 of my 32 possible great grandparents, 28 of my possible 64 great grandparents, and 30 of my possible 128 5th great grandparents. When looking at my personal family tree I have 26 of my 32 possible great grandparents, 36 of my possible 64 great grandparents, and 49 of my possible 128 5th great grandparents; there are 6+8+19 = 33 more ancestors to add to Wikitree.
My personal research tree has only 15 people at the 14th great grandparent level and there are only 13 people who appear more than once. My Wikitree pedigree has 341 14th great grandparents and 177 people who appear more than once.
I intend to work on increasing my tree completeness at Wikitree and collaborating with cousins on distant genealogy.
