I'd be grateful for information about the birthplace and family of Fred Ruf, born 17 February 1892 in Russia. His WWI draft card gives his mother's residence as Kulalaka; his WWII draft card gives his birthplace as Kulalinad, Kamishinka. The nearest place I can find to these spellings is Kulalinka which does seem to have Ruf families. Grateful for any help!
