Jakob Gross was Ari’s 6x great-grandfather, and he was a tailor. He was born in about 1780 in Poland. He married Esther Brajna Grün in about 1815, and they had at least six children. Esther died on 24 Nov 1843 in Kalisz, Poland, and her death record says that she left five sons and one daughter.

Jakob’s son Salomon was Ari’s 5x great-grandfather. I have managed to trace some of the other children of Jakob. A son Majer, a journeyman tailor, died in 1847 at the age of 27. Jakob’s son Markus married Mindla Wanna in 1842, and their daughter Machle Krecle was born in 1851. She married Moizes Szleper in 1869 and died in 1908 in Kalisz. Another son of Jakob’s, Ayzyk, married Malka Bajdenkopf in 1852 in Zagórów, Poland and died in 1884.
