Ha, so true. I think I know the story of what happened with Larry and Rena based on what I've been able to find. I know what they did for a living, I've seen pictures of their houe, and so on. They were considered "the black sheep" of the family. Therefore, only one of Larry's nieces knew anything about them. She tried to stay in touch with them, but it didn't work out so well.
Thanks as always for your quick help. Sometimes you provide that one dam-busting clue that is so sorely lacking in my research.
