I am writing hoping that this will help you as much as it will help me. My great grandfather is Hiram G. Diffenderfer. He was born in 1845 and died in 1925. I do not know the name of his mother or father but I do know that he is buried in Salunga Mennonite Cemetary. I believe that possibly there were 2 wives, the 1st being Clara Cook 1849-1907 birth and death. I do know that they had 6 children. Second wife being Thereasa V Diffenderfer. I am not sure what the V stand for. Any info that you have will be greatly appreciated.
