Your grandmother Eva was the sister of my husbands grandfather, Adam Callaway. He must have been named after his father.My husband,Don, and I visited her one time when we went to Milwaukee to see his grand father.She was delightful! Don's mother was named after your grandmother and she married Clarence W. Callaway.They had two boys, Don and Jerome.My husband is 71 years old.Which one of Eva's children was your parent? Adam Klopfer had three sons and one daughter.Their names were Joseph, William, Edward and Eva. Don cannot remember his grandmothers name. So you and Don must be 1st cousins once removed.
