Name suggests his father was Meyer Ucko rather than Joachim Abraham Ucko.
I think this is confusing the date of death of a different Löbel Ucko - who was the son of Joachim Abraham Ucko and Lore Ucko.
He is married to Charlotte Bial.
They got married on January 20, 1819 at Miejsce, Opolskie, Poland.
