Charles Hafner b.1888 Ohio d.1933 Ind.

I am looking for information on my great and great-great grandparents. Charles Otto Hafner was my great grandfather, I believe born in Antwerp Ohio. Married to Virginia Galimore. His father was ( I believe) Otto Hafner who was married to Anna George. They had three children... Charles, Mary, Anthony. Does anyone have anymore info on this family. They seem to have disappeared on me. Places, Dates etc. Thank you. Phill
