Judah (Lehman) ben Abraham is mentioned 16 times between 1651 and 1676. His designation in the Stühlingen family tree is '1.3.1'. His father was Abraham (From) ben Isac, Bickert.
Lehman seems to be the son of Abraham - Ofteringen. He led the life of a minor money lender and cattle dealer at the margin of the Jewish community. He was shortly under protection from 1660 to 1662, first in Stühlingen, and when he fell in arrears, in Schwerzen. .
