Answer 2

It appears that Elizabeth Hysell is the daughter of Thornton Pound Ida Belle Tryon, but he was born about 1867 - you have this linked to a man b. in 1920's?  Daughter Elizabeth (Caroline Elizabeth) married Lauren Hysell, those are HER children, and Thornton's grandchildren in the census you noted.    It looks like Lauren G was a Veterinarian and he appears to have died in 1938.  But the death record is limited.
