Ethel M. Coffey was the second to youngest child and last daughter of Rev. Jasper Hill and China Frances Culp Coffey. See here and here for earlier blogs about this family.
I have found only three children for them: Jasper Daniel, born Apr. 14, 1909 in Gentry Co., died there on Feb. 4, 1973 and was also buried at Grandview. Second was Omar B., born Mar. 8, 1911, Gentry Co., died on Jun. 18, 1986 and was buried at Grandview. Their third child was Margaret Frances. I have no further information about her.
