 After meeting his future wife Vivien Dayrell-Browning, Greene was baptised into the Catholic faith on 26 February 1926, and they were married on 15 October 1927 at St Mary's Church, Hampstead, North London.The Greenes had two children, Lucy Caroline (born 1933) and Francis (born 1936).In his discussions with Father Trollope, the priest to whom he went for instruction in Catholicism, Greene argued with the cleric "on the ground of dogmatic atheism", as Greene's primary difficulty with religion was what he termed the "if" surrounding God's existence.
