 It is believed that the family went there from the city of Ulm, Württemberg, and that for this reason the best-known progenitor of the family and some of his immediate descendants, as well as certain others, called themselves "Ulma-Günzburg".It is also an Ashkenazi Jewish surname.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.
