Mr. Barstow had two children with his first wife, Eileen Green Barstow, before she died. In 1958 he married Joan Beique, with whom he had three children. They bought a house in Chestnut Hill that had been built in the early 1900s. Mr. Barstow, a self-taught architect, put a major addition on the home.
As an active member of the Chestnut Hill Community Association, he organized the cleanup of the Mermaid Loop Station on Germantown Avenue in 1979. The abandoned building was filled with sewage and trash. With association backing, he hired teenagers to transform the station into the Trolley Barn, an ice cream and soda shop.
Mr. Barstow volunteered as a counselor at Graterford Prison. For 40 years, he was a first reader and active member of the Christian Science Church in Mount Airy.
He was an avid golfer, enjoyed sailing in Nockamixon State Park in Quakertown, and for more than 10 years was a member of the Centennial Singers in Warminster.
After he and his second wife divorced, he married Elizabeth Turner Keeler in 1990.
Besides his wife, Mr. Barstow is survived by daughters Anne Hardy and Donna; sons Peter, Scott, and Allen; three brothers; four grandchildren; and four great-grandchildren. He is predeceased by his former wives.
A memorial service will be at 1:30 p.m. Saturday, Feb. 11, at Ann's Choice retirement community, 30000 Ann's Choice Way, Warminster, Pa. 18974.
Donations may be made to Ann's Choice Benevolent Fund.
