Okay, here are some more hints. I figure maybe Sally's Mom got remarried, or for some other reason, she had a different last name in the census. I cannot find James in the census prior to 1940 either.
So, this is perhaps her husband Robert in 1940, notice he is listed as widowed with a son, Robert Jr.https://familysearch.org/pal:/MM9.1.1/KQLZ-DJX
This may be the son in 1930, living with a "Taddis" familyhttps://familysearch.org/pal:/MM9.1.1/X7HV-Z9G
Here is Robert sr.'s first marriagehttps://familysearch.org/pal:/MM9.1.1/FFR3-LPJ
Here is Sally's obituary
