I am also a DePew. My Grandfather was Claude Kenneth DePew, I believe he was born in Renton TN. He married my Grandmother Jennie Effie Booth. Their Children are Patricia, Judith, Kenneth, Robert William DePew (my father), Anne, and Dixie.
The only other piece that I have to offer of the DePew line is another name to the brothers; William.
I would so love to know more.
