I am fairly certain that we hail from the same Fetzner family!
I have:Margarthe FETZNER b. 27 Jan. 1801d. 20 Feb 1829.I do not know exactly where she was born but she married Franz-Anton WILLHAUCK of Untergrombach on 11 Jan 1824 in Untergrombach.She had four children before her early death.
I do not know her parents names yet, although I just received this information yesterday so I am just beginning my work on her.
Let me know about your Untergrombach FETZNERs..I also am looking for DITTLERs, MORITZs and SCHNEIDER.
