In my blurry eyed state last night, I forgot to check Family Search...duh! They have a transcribed death record for Freda Mae Millard, which provides the extra bit of info that she died in Lamar County, Texas.
When I entered Freda Mae Lee in Family Search, up pops a 1930 census entry for a Freta M. Lee in Delta County, Texas. The entry notes that Freta was born in Texas to John and Evie Lee. I usually cross check difficult to find census entries in Family Search. They seem to cast a wider net when searching, which is sometime good but sometimes bad...too many returns. In this case, it was good.
So now I have a bit more info to track a birth record for Freda/Frita and marriage for James and Freda to see if I've matched the right James to the right Freda.
