My grandfather is Wallace Rolley Bretz Jr. His father was Wallace Rolley Bretz. His granfather was George W. Bretz, whose first wife divorced? and they had Tom Bretz, Wallace Bretz, and a half sister. However, Grandpa and I don't know if the half sister is from George or his first wife. She did marry again and grandpa says she took the name of Elbert Grover? All from Ripley NY. Grandpa does remember the half sister of Tom and Wallace, which would be his half aunt, to have lived in Erie, Pennsylvania and she was an awesome pianist. But cant remember her name. Perhaps this could be the missing link?
