I find this interesting as I have seven ancestors who fought in the Revolutionary War, and one of them was on the British side who was captured by colonials in 1777 and stayed in America after he was released.
Same here, although I don't know what the actual number was. A 5th great-grandfather who was born in Newtown (now part of Queens), Long Island was a Lieutenant in the 2nd Regiment Dutchess County (NY) Militia. He's listed in the DAR Patriot Index. There were 3 or 4 more with the same last name that were mustered into that same unit. Another 5th great-grandfather, born in Germany, first settled in Pennsylvania, then joined up with the Loyalist unit called Butler's Rangers. He eventually went to Canada. I also had other loyalist relatives. One of the sons who served under his father in the 2nd Regiment, left this country after the war, settled in Canada, married the daughter of a Loyalist from New York. His father wrote him out of the Will.
