You apparently have information on the descendants of George Hoffman Aird, which I dont have. But I have earlier information.
He was born in Quebec City 1820-08-17, son of George Campbell Aird and Marie (Mary) Luisa Hoffman. He died at Brantford, Ontario 1899-03-03. References: Birth registration, 1820, George Hoffman Aird, Anglican Catherdral, Quebec. Death registration, 1899, George Hufman Aird, Brant County, Ontario.
George Hoffman Aird was one of at least 8 children: Mary Louisa 1816, Rosina 1818, George Hoffman 1820-1899, Adam 1822, Edward 1825, Elizabeth 1827, James 1829, and William Henry 1832-1865.
George Campbell Aird was born in North America about 1796 and married Marie (Mary Luois Hoffma 1815-01-07 at Quebec (Ref: Marriage registration Aird/Hoffman, St. Andrew’s, Quebec.).He appears in the Quebec City Directory of 1822, p 138.He was a Shipwright and Tavern Keeper.
George Campbell Aird was a son of George Aird and Lizet Kay.george Aird was born at Kilmarnock, Ayrshire, Scotland 1759-03-23 and died about 1805, probably at St. Louis, Missouri.He was an Indian Trader and was at Michilimakinae.One early theory, which a cousin and I have determined is almost certainly wrong, was that his wife was possibly a "bush wife" -- a native who was later abandoned.We are following up on this, but it appears that Lizet Kay may have been born in Scotland or at least her parents were.We have found what appears to be her brother as witness at some events in Canada -- but more research is required.

George Aird was a son of John Aird and Ann or Anna Campbell. John was born at Kilmarnock, Ayrshire 1719-03-26 and Ann was born at Riccarton, Ayrshire 1719-06-29.They had at least 13 children.At least two are known to have died in infancy.It appears that at least three came to Canada -- both in the military and/or as Indian traders, within a few years of 1780.
This is one of three lines of AIRDS I am tring to link up, where the lines are almost certainly related.The three lines are - descendants of John Aird and Ann (Anna) Campbell of Kilmarnock [the one discussed here]. - descendants of William Aird and Mary Hunter of Kirkmichael who migrated to Quebec in 1829 [my line]. - descendants of John Aird and Mary Dobbie of Kirkmichael.
We need a living male AIRD in each of these lines to take the DNA test to determine relationship.
