re: Elizabeth Tang. My gr gr grandmother is Mary Jane Tang, daughter of John Tang and either Patricia or Caroline Foster depending. I was told there was a Foster home in Bonfield and I believe this may be the case as I have seen where there are 5 "Tang" children with head of household haveing a different last name. ( noted on census)
The other part is that though it says Denmark, I hve also seen Germany and possbly descended from the Dutch settlement from Pennsylvania (Harrisburg). And finally, Tang is possibly of "Chinese origin" BUT German variations do show Tange.
