The SSDI lists Clytheria E. Sellers, born 9 Dec 1916, died 16 Jan 1997, last residence Hillsboro, Montgomery Co., Illinois.

There is a user-submitted tree on Ancestry.com that lists her as marrying Lyman Edward Sellers in 1937, but that seems impossible since he was her uncle.

In 1930 she is listed in St. Louis, Missouri, as Clytheria Sellers, age 13, b. Minnesota Illinois Minnesota, niece, with her father’s sister Hester.
