If I have the correct Adams.... your grandmother was Lillie Mae Hare, daughter of Thomas Hare and Susan Annabell ???. She may have married someone last name of Dettweiller first as in the 1930 census she is married to Lewis Adams but William (4 yrs) and Clarence (2 yrs) Detweiller also live in the household. Later, in 1940 census, Lillie is married to Ruben Davis. Both Detweiller children now have last name of Adams, so might have been adopted. Other children from 1940 census are: Cathlene Adams, 9; Lonie Jean Adams, 8; Margaret Adams, 7; Christine Adams, 5; Joe Ann Adams, 3; Harriet Adams and Thomas Adams, both age 1. Is this your line?
