I found Patsy as a surviving daughter in both Helen and Pearl's obits found at http://www.geocities.com/milamco/

WILLIAMS, Pearl Pinkerton of Milano. . .
SURVIVORS: Daughter & son-in-law, Patsy & George Trammell of Friendswood; sister, Helen Rush of Milano; 3 grandchildren; 6 great-grandchildren.
and
RUSH, Helen P. (Pinkerton) Wilson of Milano. . .
SURVIVORS: Daughter & son-in-law, Patsy & George Trammell of Friendswood; 2 sisters-in-law, Annie Pinkerton of Salty and Beulah Pinkerton of Austin; 3 grandchildren; 6 great-grandchildren.

Pearl and Helen were sisters. Does anyone know which one was the mother of Patsy who married George Trammell?
