Hi, I know something about Francis Mackay's descendants. Among them, he had a son, Capt. Samuel Mackay, who came in Canada around 1775-80, helping the British Royal Crown after the invasion of Quebec city and Montreal by Americans. He is my ancestor and I would like to know more about him.I have the list of all my ancestors, untill my grand-mother, Adrienne Mackay. They were involved in "the war of Patriots", were closed to the Louis Joseph Papineau family (prime-minister of Canada) and to the Globenski family (Seigneur of Domains in Quebec) around 1700-1800.
