Joan Mary Wayne Brown
Mary Gervaise, Hilary Wayne and Bellamy Brown was the pseudonym of Joan Mary Wayne Brown, a prolific writer of romance novels and books for girls, publishing over 70 books. She was born on 21 April 1906 and died on 26 April 1998. A bout of anaemia caused her to pursue writing at the age of 18, rather than attending college.
Her children's books were written as Mary Gervaise. Most of them are school stories, but the Georgia and Belinda series are pony books.
