Hugh, I just went and looked up the 1920 census and got a big surprise. Lillie was married to Will Aaron but it much have been before she married Chester Little. ON the 1920 census Chester and Lillie are living in Hunt County, Texas. They are listed with no children but listed as step-children of Chester are Glendale Aaron, age 3, and William Aaron, age 1. These must have been Lillie's children with Will Aaron. Evidently he died about 1919. That would make the marriage of Chester and Lillie later than the 1930 census indicates.
She evidently married Will Aaron after the 1910 census and he died before 1920, making it impossible for me to find her listed as Lillie Aaron.
Thanks so much again. It is wonderful how so many times asking for the help of others can open up something. I have worked on this for 2 months now with no progress and today the flood gates are open.
