Sometimes this kind of thing can help determine relationships between families or at least hint at the family structure. Below is an example which nailed down a relationship which seemed clear based on naming patterns, but which needed one more piece of evidence. I had already determined that a particular couple named David and Serka Pikholz were almost certainly the parents of a certain Yitzhak Pikholz.
Not only would I have been less likely to reach my conclusion if I only had one or two births of Yitzhak and Frimet's children - without the full set of birth records, I probably wouldn't have attempted an analysis based on house numbers!
Another example is the family of Peretz and Perl Pikholz of Skalat. They were named in the birth records of the grandchildren that they had from their four daughters - Chaje Nesie Spacierer, Basie Ruchel Scharf, Sure Kornberg and Blime Brandes. Below you can see parts of some of the births which were recorded in Skalat, Zbarazh and Tarnopol.
|Three records show the parents Peretz and Perl Pikholz. One shows only Peretz.
When the Lwow records became available, I saw in the JRI-Poland index that while six of Blime's seven children were born in Tarnopol, one - the fifth - was born in Lwow. It struck me as curious that the family had four children in Tarnopol, then one in Lwow and two more in Tarnopol, so I ordered the record, just to see what would turn up.
