GÜNZBURG


Eliezer "Lazarus" of Ulm, son of Jechiel,1 (possible son-in-law of Abraham, with lineage back to Coburg), likely had children: Simon and Jakob. In 1499, when Jews were expelled from Ulm, he likely moved to Günzburg.


Research Notes

1. There appear to be two primary sources for the name Jechiel.
While both provide Jechiel as the grandfather's name of Shimon, they have important discrepancies: different father names and no reference to Porto in the latter case. Nevertheless, there is an additional source, which corroborates Shimon's father's name being Eliezer: the Memorbuch of Pfersee. It lists Shimon son of Reb Eliezer Ulma from Günzburg. Taken together, the tentative conclusion here is that Shimon is the son of Eliezer, son of Jechiel, with no assumption about Jechiel's origins.
