Is there a chance you know a name of either parent of Gerald E. Sr.? I could look for him on the 1940 census
and get a clue to where Bettie may have been from. So far I've only found Gerald E Simpsons on the Calif. census, not Kansas born in his year. Maybe his family moved to CA when he was a child and Bettie green was from there. Do you know Bettie's middle initial or name? you can email me privately at mhop7@aol.com
