I'm not related, but I'm trying to see what I can find for you online.
Maybe you can explain something I found: Hattie Flowers and George Flowers (although the wrong age?) are listed as living with Lillian Choate and her family in Precinct 7, Jefferson, Texas in the 1930 US Census. Hattie is listed as sister-in-law and George as brother-in-law. From this I assumed that Lillian Choate was Lillian Flowers.
However, from Texas birth index info, and her son Jack's obit, Lillian is Lillian Ruth Kaiser.
Was Lillian Flowers married to a Kaiser previously? Or is this not the family you're searching for?
PS: I think that George's age may have been a misprint, because he's listed as a "barrel nailer" in an oil refinery -- if he were ten, he seems to young for that??! Wouldn't he by law have been in school?
