I would sort of like to know if any of mine were in the Revolution. A good chance but don’t know.
Three of my Great Grandfathers fought for the Confederacy and I am proud of them. The Forth was a Methodist circuit rider who spent at least two years at a Confederate camp.
If any of your relatives ever joined the DAR or the SAR, it may be possible to identify an ancestor who either served in the Revolution or at least supported it ("Patriotic Service" such as taking an oath of allegiance or supplying beef to the army, etc.). If you know the names of any ancestors who were alive and the right age at the time of the Revolution, try to find them in the DAR database.
The DAR site has a search page for patriots.
If you know who your ancestors were during that time you can search.
You can use ancestry.com to find out if you don’t know.
