I asked Ken if he knew anything about the Frank you are inquiring about. He said his uncle was married to Eileen (can't remember her last name.) They had a boy named "Robby", perhaps for Robert...Ken was a junior in high school when they married (around 1948/1949.) Frank and Eileen lived in Vallejo, CA for a short time, and Ken thinks that's where Robby was born (although he may have been born in Cottonwood.) Ken's two uncles (Steve and Frank) had a ranch in Cottonwood, Arizona before either got married. The only thing we can think of is it may be a cousin? As I go along with my research I will keep an eye out for your "Frank". Your name indicates you are a Rebstein...are your Rebsteins from Texas or Arizona? Keep in touch as we go through the searches.
