I am currently working on a family tree. I am a Great-granddaughter of Chester Eberhardt. I don't have anything for dates but I can add to this tree. From what I have found, Chester Eberhardt and Viola Clay had 5 children. Walter, Chester, Doris, Patricia, and Charles. Charles then had 5 children. Charles Eberhardt Jr., Lisa, Peggy, James, and Cindy.
