Naming patterns are often confusing. We have a whole bunch of Ss down the line. Great grandfathers Szloma, Szymon, grandfather Zalman/Solomon, uncle Sidney, deceased 1st cousin Steven, living 1st cousin Steven, etc. The lesson : without being told who everyone was named after, it would be difficult to determine. It does help trying to match up deaths. For example, when my great grandmother died, my grandmother named her next born after her mother.
