Mrs. Lynch, whose maiden name was Gaffney, grew up in Cedarhurst, N.Y., and followed her creative muse to New York City, where she received an associate's degree from the Tobé-Coburn School and worked in fashion. In 1970, she married Raymond "Skip" C. Lynch Sr.
The two moved to the Philadelphia area and settled in Wyndmoor. Mrs. Lynch ran two businesses in Chestnut Hill - Nina Needlepoint from 1971 to 1976, and Business Unusual from 1972 to 1982. The latter was a cottage industry that marketed a dip and dressing food product.
Mrs. Lynch was a passionate advocate of service-learning because, her family said, she believed it would help schoolchildren become useful members of society.
What started as a grassroots effort in several schools is now a citywide network of support, enabling teachers to guide students through a yearlong project designed by the pupils themselves.
In 2007, on the organization's 20th anniversary, Mrs. Lynch was honored for her service in an event at the Philadelphia Navy Yard chaired by former Gov. Ed Rendell.
Mrs. Lynch also was a productive potter, jeweler, and photographer, working locally and in a studio in Bridgehampton, N.Y.
Besides her husband, she is survived by daughter Daphne G.L. Fifield; son Raymond "Rummy" C. Lynch Jr.; five grandchildren; and two sisters. A brother died earlier.
A memorial service will be held at 11 a.m. Friday, June 13, at the Church of St. Martin-in-the-Fields, 8000 St. Martin's Lane, Philadelphia. Burial is private.
