Rabbi — Parnas (Vorsteher 1542-1582), Gove (Kastenmeister 1579-1582)
House: “Eichel” (shortly), later in “Korb”
1536 mentioned as Rabbi Alexander z Eichel, son-in law of Rabbi Josef (Mantua)
1546-1577: He is appointed as “Vormund” (guardian, custodian) by several parents of their (orphaned) children (in at least 10 cases) [cf ET]
1556: He pays for his brother’s son named Moshe and for Samson who were both living in his house.
1557: The converted Paulus Renatus (who was originally named Leib b’ Maier Oppenheim z grünen Schild z Rindsfuss) is accusing him (Alexander) of sexual misbehaviour. He is arrested and tortured, but he did not confess. Afterwards Paulus’ accusation turned out to be false.
1575 — [Pr(otokolbuch) 5336, nr 55:] his signature “Alleksander b’’ Jizchak ha-kohen’
1577 — [Ele Toldot, UP 1577-144 bis 157:] Alexander has a brother named Josef from Weisenau, who was as well involved in the Paulus Renatus law-suits — [¿ were their parents living in Weisenau (near Mainz), before they moved to Frankfurt?]
children:
# Leib/Leiwe b’ Alexander z Korb (d. ca 1607) >>
# Bräunchen b’ Alexander (d. 1581?) >>
# Moshe b’ Alexander z Korb (d. 7.9.1622) >>
# daughter, married to Salomon (in) Günzburg
[NB: It is not conclusive from which marriage these children are, but most plausibly Hanna is the mother of all of them — though Kreinlain was afterwards mentioned as the mother of Leib and Moshe — cf ET Be.1584]:

sources and questions to be researched further:
¿ — how is his relation to the original Goldschmidt family?
On the website of the Frankfurt Jewish Museum ®41 Alexander’s son Moshe is mentioned as a Nephew [=‘Neffe’ in german] of Josef, the husband of Mostel Goldschmidt’s daughter Shprintz.
Josef [segal] cannot be a full brother of the cohen Alexander — maybe a step-brother via an earlier mariage of one of their parents? — or maybe a step-brother of the mother of Alexander’s son Moshe? — or were they brothers-in-law via [unknown] siblings? — or should the term ’Nephew/Neffe’ be considered in a broader sense — for instance: was Alexander’s mother [Gotta] a sister of Josef’s wife [Shprints] or of Josef’s mother [NN] , etcetera — unsolved as yet — but along all these conjunctions Alexander seemingly got his mention with the surname ‘Goldschmidt’ in a way comparable with how Josef, Shprintsz’s husband, got this surname.

¿ — Is the same unusual origin Mantua more than a coincidental relation between Hanna b’ ‘the Rabbi’ Josef mi Mantua z Eichel (who was married ca 1535 to Alexander Goldschmidt), and ‘the Rofe’ Moshe b’ Lev Lucerna mi Mantua z goldenen Schwan (who was living since 1570 in the same house as Josef Goldschmidt)?

[of course the info from Ele Toldot ®27 and other sources is far from complete — and even these scarce data may not all be correct]
