My name is Debbie Greer and I am doing my family history on the Wolkersdorfer side of the family. My GG Grandfather Christoff Wolkerdorfer came to the USA in 1875. He was married to Cathrine Erich. They both are from Germany. My Grandmother was Olga (Wolkersdorfer) Tice, Linton. She lived in Ohio and died in Florida. Can you help?
