Can you tell us the name of his spouse(s), approx. marriage date(s), where he located after leaving S.C., approx. when he left there, anything about his parents, names of any of these daughters, when and where born, when and where the son, Harry, was born, anything about Robert's occupation(s), when and where he died, anything he may have disclosed about military service (he would have been draft age re: 2nd WW), siblings, etc.?
If you can fill in any of these blanks, it would be helpful since you haven't given much to work with here. Don't dispair; if you work at it, the answers will come and you will find what you are looking for.
