While at Repton, Fisher met Rosamond Chevallier Forman, who was the daughter of a former master at Repton and a granddaughter of S. A. Pears, a famous headmaster of the school. They were married on 12 April 1917; they had six children, all sons. Webster writes that the marriage was lifelong and mutually supportive. By the early 1930s Fisher felt that it was time to move on, and was hoping for an appointment as a parish priest, preferably in a rural parish.
