Ruth died jan 10 on a Sunday in 1960 in Marion Illinois. She was married to Ray Jerrells Jr. Her obit is under the name of Jerrells.
I do believe according to the 1930 census that Ruth is the dau of Emra and Eva McPhail although in her obit her parents are referred to as Mr.and Mrs. Peter McPhail.
the census has this: Emra C McPhail age 28 born in Illinois but father born in Kentucky, Eva age 24 born in Alabama, Ruth age 4 and Jean Sagee 2 both born in Ill.
Emra died Oct 1976 and Eva a month earlier. Both in Royalton, Illinois. There is also a Loren L McPhail of same town who died May of 1990.

Might be worth noting for those researching McPhail name that his neighbor is Daniel McPhail born in Kentucky age 60 and mother Mary (very blurry) born in Illinois. sons Lester, Ray,Lewis. I hasten to add all the boys names are blurry and could possibly be spelled differently.

In researching the Jerrell name I think Ruth McPhail went on to marry Ray Jerrell mentioned above.
