* Tentative (but plausible) insertion as a possible son of Josef b’ Moshe (Goldschmidt) Schwarzach. — and an eventual link in an alternative lineage between Mostel b’ Josef Goldschmidt Schaffhausen and his offspring
The exact relations between some of the first Generations are based upon scarce information and are often worked out here in just a reasonable assumption — [JG]

Baruch is mentioned as a goldsmith acquiring protection in Stadtschwarzach ®51
> ca 1537 [Quote] “…..one Jewish goldsmith, Baruch, does appear in East Franconia, who, on being received in Schwarzach in 1537, promised to live only by his craft.” — this passage is from an entry in “The Jewish Encyclopedia” ®52, refering to an article in “Monatsschrift” ®51 — Later I found the original text of the quoted article (Monatschrift 1880, Vol 10, october, p 463) ®51 by Heinrich Epstein, where more specifically was mentioned that Baruch’s father was already living in Schwarzach! And it seems questionable that it was in the later quoted year 1537 — for that matter: from the article’s context must be concluded that this fact concerns an ordinance (likely dated before 1537), issued by the prince-bishop Konrad II von Thüngen who was reigning East-Franconia 1519-1540]:
“…..In einem Erlass vom Jahre 1537 verbietet Konrad auch das Beherbergen der Juden …… Mittlerweile werden mehrere jüd. Familien auf Lebensdauer in Schütz genommen und ihnen ein Wohnsitz angezeigt. Interessant ist die Inschutznahme eines ״Juden Baruch”. Dieser nemlich war Goldschmied von Beruf und erhielt gleich seinem Vater die Erlaubniß, in Stadtschwarzach zu wohnen. Er verspricht, nur seinem Handwerke zu leben und mit fremden Juden nicht zu verkehren. Sollte es den Bisch. gefallen, ihn aus Stadtschwarzach zu ״versetzen", so wolle er sich fügen. Ueberhaupt verspricht er unbedingten Gehorsam”.
Furthermore I found another ordinance issued by the succeeding prince-bishop Konrad III von Bibra (1540-1544), verbally: “Anno 1541 am dinstag nach Margarethe hat B Conrat von Bibra Baruch Juden Goltschunden zu mit ainer masen zu Schwartzach in der stat zuwonen vergont bis vf widerruffen Recepta in 2. diuersarum formarum Conradi fo. 28.29.” (meaning: 19.07.1541, Bishop Konrad von Bibra has allowed the jew Baruch, goldsmith, to reside till revocation in the town Schwarzach am Main) [cf: Fundort in der Hohen Registratur: Standbuch 1011, Folio: 412r, Schreiber: Lorenz Fries]

These quoted ordinances give cause to assume that this Baruch might be a son of Josef b’ Moshe Goldschmidt mi Schwarzach — and maybe as well the forefather of several Goldschmidt generations where Baruch is a frequently recurring name [e.g: Baruch Daniel] Shmu’el b’ ? Goldschmidt Shtuckart segal (b. ca 1575, d. ca 1624 Witzenhausen) and of [Moshe] Baruch/Benedikt b’ Jehuda-Leib Shtokkert (b. ca 1590, d. ca 1643 Kassel) — [cf their record sheerts]

Of course there are other possibilities — but it may be ruled out that he is the same person as the son of Josef’s brother Isaak Aschaffenburg, who was also named Baruch, while this other Baruch [b’ Isaak] must have been much younger.

[NB: — “Stadtschwartzach”, nowadays usually named Schwarzach-am-Main is situated 20 km east of Würzburg, 70 km northwest of Nürnberg, 85 km south east of Aschaffenburg]
[As a side issue may be considered how the name Baruch has entered in the Goldschmidt family — seemingly via one of the unknown (NN) spouses of Mostel or his sons -- none of Mostel’s four known sons-in-law had this name]

NB — this Person Sheet represents a generation in a “hypothetical offspring construction” — to bridge time gaps in the lineage, between the son(s) of Mostel Goldschmidt Schaffhausen and his identified later descendants
