Thanks for your help.
I also believe that they likely married (if at all) in Missouri...although I also cannot find a marriage for them.
Based on all info in hand, I still think there is a good chance this Joseph Camara is my "missing" Uncle Joe. I just am stuck on how to prove it since there is no marriage or divorce record for he and Mildred. I have also hit a brick wall on ANY records for the son Lee H. Camara...he seems to have vanished as well!
I did find a later divorce record for a Mildred Camara - from an Abel Marks in Santa Clara California in 1967. Based on timeline she could be the same Mildred that married (or at least took the name of) Joseph Camara.
I know that Joseph married (or is it remarried?) in Sacramento, California to a Betty Maudine Walters in 1953. I also know that he died in Sacramento, California in 1980.
Not sure where else to go with all of this...any siggestions would be greatly appreciated!
