Does anyone know the source of this, that the father in law of Moses Bingen was Mayer Warschler?
Randy Schoenberg can you add any information on this?
I tried to find, in no source that I was looking for, it was written who Moshe Bingen's wife was.
Ok, I think I found it, it is based on this Epidat: http://www.steinheim-institut.de/cgi-bin/epidat?id=ffb-906&lang=de
which is probably his sister, and has her mother as daughter of Mhrrm Werschler,
Problem with this page?
