While anything is possible, it is unlikely that the record is fake. There were some
3,000 Jews in Mogielenica; the last name, Goldstejn, is very common. It might have
been a cousin, named after the same ancestor, or even an unrelated person. Wife's
name can be a coincidence as well, unless it is very unusual. If the record listed
surviving children, in addition to wife, that would be an additional proof. In the
absence of corroborating evidence, this may remain a puzzle.
