She met and fell in love with Dr. John C. "Jack" Colston, a Hopkins Hospital physcian, whom she married in 1955.
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.
After college, she published several short stories in local magazines, family members said.
She and her husband later moved to Devon Hill in North Roland Park. They were world travelers, and in addition to Europe, had visited India, China, and South Africa.
Graveside services are private.
In addition to her husband, she is survived by two sons, John E. Colston of Glyndon and Will F.C. Colston of Bethesda; two daughters, Debby C. Furcolo of Chevy Chase and Letitia L. Colston of Seattle; and nine grandchildren.
