I saw your message on the internet about John Hoffman and Henry Huffman -- I assume you mean the ones who came from Germany (Siegen) in 1714 to Virginia.
My family is related to one of these two brothers, but I have been unable to fill in a few gaps.
My grandmother was Otelia Huffman, married to David Nathaniel Embrey.
Otelia's parents were William David Huffman and Sarah Elizabeth Monroe.
David Huffman's parents were John Huffman and Delilah (?).
The John Huffman who married Delilah is descended from one of two brothers who came in 1714. However, I have been unable to make the link from my great great grandfather John Huffman to one of the two brothers.
I have, however, been able to trace the brothers back to their ancestor, Heinrich Hofmann, who was born in 1505 in Eisern, Germany.
