C. S. Lewis
After his conversion to theism in 1929, Lewis converted to Christianity in 1931, following a long discussion and late-night walk with his close friends Tolkien and Hugo Dyson. He records making a specific commitment to Christian belief while on his way to the zoo with his brother. He became a member of the Church of England – somewhat to the disappointment of Tolkien, who had hoped that he would join the Catholic Church.
Warwick
J. R. R. Tolkien seems to have been very influenced by Warwick (where he was married in the Catholic Church of Saint Mary Immaculate) and by its Mercian connections: Lynn Forest-Hill, in an article in the "Times Literary Supplement" (TLS 8 July 2005 pp 12–13) argues cogently that two important settlements in Tolkien's work were modelled on Warwick — Edoras closely on the early town, and Minas Tirith more remotely on the Norman; and that aspects of the plot of "The Lord of the Rings" are paralleled in the romance known as Guy of Warwick. Christopher Tolkien, in "The Book of Lost Tales", stated that Kortirion, the main city of Tol Eressëa, "would become in after days Warwick."
