Yes. My most well known ancestor (at least among the family)was a Justice of the Peace and was known as "Col." but his official record says that he supplied horses and wagons to the armies and participated in the Letters of Correspondance. He was probably in his 50s at the time, so a little old to be tramping in the field. But, my mother's family were female, or Quakers, or aged -- so out of the running as far as I know.
I found several of my ancestors in the pension rolls. They were from North Carolina, South Carolina, and Georgia.
Something really interesting is several of them mentioned among their military actions, “The Florida Campaign”, yet I have never heard of any actions in Florida during the Revolution.
