Re: Troys - Westmoreland County, PA
I checked around on Ancestry.com for your Charles Troy. I found several census after he was married and some military information but no parents.I even checked other trees but none had his parents either.
I might suggest that you send a request for a death certificate from the state of Pa.It might have parents listed. I doubt that you'll find a birth certificate from there though.You can also get records from the Government since he was a vet of the Civil War.
