Francis Faile opened his one-chair barbershop on Lancaster’s Grace Avenue in 1967, and he was still cutting hair there up until nine weeks ago. A small-business institution in the Erwin Farm community, Faile died Tuesday, two months after what he thought were kidney stones turned out to be inoperable cancer. He was 92. “He was content and never lost his great smile,” said his son, Frankie Faile.
