Do you have any idea where your James Heffelfinger was born in Virginia or who his parents might have been. I descend from Jacob and Elizabeth (Burgess) Hefflefinger of Henry County, Virginia. They could not be your James' parents as they didn't marry until 1815 but Jacob did have at least two brothers whom I've not been able to identify by name.
My gg-grandfather was also a James Hefflefinger but he wasn't born until 1835 and he died in 1832 in Virginia due to disease. I have copies of his Confederate Army records on which he is sometimes listed as James Heffinger.
