The LDS site shows that Eula Mae Adams married William Knox Regeon on 24 May 1919 in Hawley, Jones County, TX.
Checking the 1910 Census for Jones County, TX, 3 J Pct., ED 138, Pg. 21A I found this:
Adams, Elis, age 32 Married 12 years, TX, KY, KY, Farmer , Lilly, Wife, age 28, Married 12 years, TX, AL, TX , Vernie, Son, age 11, born TX , Eula, Daughter, age 8, born TX , Maud, Daughter, age 5, born TX , Jack, Son, age 14/12 (or 17/12), born TX
The LDS site also gives the parents of Eula Mae Adams as J. E. Adams and Lillie Gibson.
