I am your father's second cousin. Your grandmother's sister, Loula Wiles Hutchison Nixon, was my grandmother, my father's mother.
Your grandfather,Wilmer Heery,and my father, Robert Gray Nixon, Jr., were first cousins which, I believe, makes George and I second cousins.
George and I spent time together from time to time as children and were in the Scouts together in Decatur.
I last saw George some years ago when we were at Maggie Valley and we spent a weekend with with him and Betty at Highlands on our way home to Florida.
I have found out much information about the family "mystery man,", Robert Neal Hutchison (Uncle Robbie), which I will be happy to share with you if you are interested.
