Jonah (Jonas) ben Meir, Gugenheimb is mentioned 23 times between 1664 and 1716. He died around 1695. His designation in the Stühlingen family tree is 'G1.3.2'. His father was Meir (Marum) ben Jacob, Gugenheimb.

Jonah is the son of Marumb ben Jeckhuff. He seems to have been the main support for his mother, after his father's death. It is likely that he was quite young at the time of his father`s death. The situation with Jona`s descendancy is similar to that of Jacob ben Meir GH. It is also supported by [R65; 09.29.1691]. Jonas and his brothers all were initially under protection in one of the surrounding villages, until a slot became available in Stühlingen proper. .
