Fred,
Gladys I. Rainwater died in Emenence, Chambers, Texas, 31 Oct 1976. I am not sure when they moved there. I know they lived in Liberty, Tx when my daughter-in-law's father was born in 1938. I have not been able to find to much on the Rainwater line. If I run across any more information I will let you know.
