Great stuff...may I inquire if that ancestor was of German or Scottish (or other) background? I ask because many of the Western PA colonists were German, and many of them were pacifists; they recruited others to form militias out there, with Hugh Mercer one of the Scots who went there to fight.
The guy must have liked a good fight, volunteering in two wars. That sounds Scotch-Irish, doesn't it? :-))
