Hi Kimberly! Ray Van Giesen was my dad, Cecil Van Giesen's, cousin. Ray was a minister in Missouri, I believe. I only met him & his family once when they visited in Kane. I was 9 yrs old but I remember he had twin sons who were 12. I'm 68 so that would make them about 71 now. They were David & maybe Dwayne. Ray's father, Melvin Ira Van Giesen & my grandpa, Archie Van Giesen were brothers. Was your father one of Marlan's sons? I don't know a lot about anyone very far back but will help you when I can.
