We had just about the best day you can in the field of genealogical research. Our guide took us directly to the relevant locations, frequently bypassing lengthy lines of cranky Poles via a mixture of Government Savvy and heavy flirtation with the armada of middle-aged lady overseers. Immediately he dialed up the original books of handwritten records: marriage records, birth records, and death records. With a tiny bit of oversight, we were permitted to paw through these willy-nilly.
First we found the marriage record for Moishe and Paja (in 1890!). From that document, which listed their parnets -- brand new information for us -- we were able to research backwards, digging up assorted marriage and birth certificates until we got back to approximately 1815, which is around when Napoleon instituted the system anyway. It was a homerun of a day.
Before this, we didn't know anything except that my great-grandfather - Moishe - lived in Czyzewo. Today I know about 15 or so more ancestors, including information about where they lived, the time they lived, and- in some instances - even their occupations. (Lots of "day workers" in there, oddly.)
I must say, there is an incredible level of comfort connected to knowing that your family came from somewhere, that they just didn't show up from nowhere. My great-grandfather came over to New York alone, which has cultivated a lone wolf image in my mind, a feeling of cultural isolation. Anti-Semitism aside, it's evident that the Schwartzes were very much part of the Czyzewo community, that they had a home.
