A former longtime resident of Poplar Hill, she was a member of the Johns Hopkins Hospital Women's Board, volunteered at the Walters Art Museum and was a member of the Lake Roland Garden Club.
She was a former member of the Gilman School board of trustees, and financially supported the school's annual Edward Fenimore Award, which honors her late brother, a Gilman student.
When she was in her late 40s, Mrs. Colston decided to go back to school and enrolled at what is now Notre Dame of Maryland University. She graduated summa cum laude with a double major in English and art history in 1985.
