The correct place name is Segendorf, now part of Neuwied. ZIRBES is a
still wide spread family name in the Rhineland. Therefore this ancestor
was not Jewish. A useful website for such information is the telephone
directory www.dasoertliche.de <http://www.dasoertliche.de>. Search for a
family name and a map appears, which shows you where in Germany a person
with this name lives.

When you look for genealogical information on the internet about a
family or a place, search for "name + Genealogie". In this case,
"Segendorf Genealogie" and "Zirbes Genealogie" will present you the
books and sources (Familienbuecher) that have been published for this village.
