I notice that your middle name is Harvey. I had Benham cousins named Don and Mary Harvey, who I visited several times in Tarkio, Mo, I think. They had a son, whose name I don't remember, but I do remember spending time with him here in Los Angeles, when I was young. A little trivia, I think he roomed with Wally Cox when he was in college. Anyway, I remember Mary Harvey very well. Her maiden name had been Mary Benham; she and my mother were very close.
Does any of this ring a bell with you? It could be that you and I are cousins. More trivia, Don Harvey had been with the unit that captured Berchtesgaden during WWII. He had found the remains of Hitler's clock in the ruins. He saved them, and had the innards of Hitler's clock in his home in Missouri. I remember seeing the clock on the wall there.
