Alexander Sutherland was my 4th great grandfather Born in Scotland 1743 - D 1843 in Grayson County VA. He came to America during American Revolutionary War to fight for British as story goes but stayed and changed sides (not proven yet) but that is family legend
Your Alexander Sutherland may be a decendent of my 4th great grandfather Alexander from Scotland. Alexander had a son named John Joseph Sutherland (my 3rd g-grandfather) He in turn had a son named John Alexander Jesse Sutherland (John Alexander was brother to my 2nd g-grandfather Francis Marion Sutherland) John Alexander Jesse Sutherland (1837-1897) I do not believe is the one you need because he was married to Susan Jane Hackler who was his only wife and outlived him.
But it could come down the line from Alexander Sutherland (most likely about the age of one of his grandsons which John Alexander Jesse Sutherland would be)
I did find an Alexander Sutherland of the American Revolutionary War (from New York area) when doing research for the Daughters of the American Revolutionary War for connection of my Alexander Sutherland to the War. But mine is from Virginia and never settled in New York. Always was in Virginia (Grayson County, Virginia)
Keep in touch because if you are looking for a Virginia connection it most likely is with a decendant of this Alexander Sutherland from Scotland. Pam Spivey firstname.lastname@example.org
