Looking for any Mauer (Maurer)/ Derby relatives. My great grandfather Derby, married my great grandmother, (maiden name Mauer). My grandmother was Elizabeth Helena Derby born 7/8/1878 in Ohio. My Great Aunt Cora Louise Derby was born 2/5/1876 in Pennslyvania. Unfortunately, I do not know my great grandfather's or my great grandmother's given names. Would love to make contact with my Mauer/Derby families & learn 'all' about the families! Please feel free to contact me with any & all info, it would be greatly appreciated.
