Johann Proziminski, a cavalry nobleman (Edelmann, Husar), and his wife Regina Meier settled in the Volga German colony of Fischer on 28 July 1765.
They are recorded there on the 1767 census in Household No. 9. The 1767 census records that Johann Proziminski was from the Polish city of Warsaw.
There do not appear to be any surviving male descendants of this family among the Volga German colonies.
