Ginsberg, Ginsburg, Gensburg, Ginsburgh, Ginzberg, Ginzborg, and Ginzburg are variants of the surname.
The Günzburg (Cyrillic: Гинзбург Ginzburg, Гинцбург Gintsburg; Yiddish: גינזבורג Ginzburg, גינצבורג Gintsburg) family originated in the town of Günzburg, Bavaria.
When, early in the emancipation period, the Jews of Russia and of Austria were ordered by their governments to adopt family names, it was natural that many of them should choose a name so respected and pleasing as that of Günzburg.
There is on record a lawsuit instituted by Baer Günzburg of Grodno against a Jewish family of that city who had adopted the same name under the decree of 1804.
[3] The river name Günz is ultimately derived from the Indo-European root *gheu-, meaning "to pour".
