The films for the 1869 Census for Saros County are available through
the Mormon Library. Some of them specifically mention Jews (Szido) and
perhaps the others include Jews also. I have yet to order them myself.
I will be glad to forward the information -- specific film numbers -- to
anyone who asks.
A big thank you to Marelynn Zipser who lives in Salt Lake and mentioned
these films on the H-Sig.
