Hugh, I am corresponding with distant cousins who are also doing research on the family and they have now traced the family back as far as Virginia around the late 1700's. The name has had various spellings, mostly Swart but they have found some of the family back then spelled it Swartz also. Until now I had not recognized any connection but I think there has been a Henry Swartz in our family research that has been forwarded to me. If I can be of any help I will try.
