Named in son Emanuel's marriage certificate.

Named as Pincus in the JRI-Poland Tarnowitz records of his 1848 marriage and the births of his children in 1849, 1853 and 1854. Named as Jacob in the JRI-Poland Tarnowitz records of the births of his children 4-7 days after each of those born to Pincus. Both sets of records identify him as a saddler and husband of Bertha geb. Fischer. I conclude that the records relate to the same father and the same children, being Jewish and civic records.
