I am David Hamblen Jr.'s half sister.
So far this is what I have. Maybe Susan can tell me if this is correct?:
David Hamblen Sr.'s Mother was Irma Cleveland Hamblen. No information known about the father.
Irma's Father was Harry L. Hamblen, and mother was Elizabeth Cleveland.
Harry's Father was Isaac Hamblin, and mother was Susan Emma Fisher.
Susan's parents were Joseph H Fisher and Charlotte Harps.
How'd I do?
