I would have thought Galician Jews were Sephardic and spoke Ladino

There are at least two Galicias in Europe: (1) the Gallego-speaking area in NW Iberian peninsula; and (2) the old Austro-Hungarian administrative region in the Poland, Czech and Slovak area (aka Galicia-Volhynia), roughly between Lublin in the north, Krakow in the west, and Lwow in the east; and a possible connection with (3) the area in Anatolia, Galatia, that was possibly Celtic-speaking mentioned in a letter of Paul in the New Testament. There have been theories the the root gal- may be the same Celtic one in all three (plus let's thrown in Wallachia in Transylvania) and Gallia, etc.

Ceci n'est pas un seing.
