Your Hans Christopher Zimmerman was born 16 March 1691/92 in Bietigheim, Wurttemberg, and he married Elizabeth Albrecht 4 Sept. 1714 in the same city. They emigrated to Virginia and both reportedly died in Culpeper County in 1757. There's a lot more information on the Zimmerman web forum. I believe one of my ancestors married Christopher's daughter Elizabeth Zimmerman in 1749. If you have any information about children, I would be pleased to hear from you.Thanks, Liz.
