In checking the Sallet book for the 1920 census, these are the counties you should look at: Berrien, Saginaw, Genesee, Bay, St. Clair, Huron, Tuscola, Arenac, Shiawassee, Lapeer, Sanitac and Iosco. These are given in the order of numbers from the most to the least. This totals 6,405 born in Russia. Regards, Curt.
