The Mantell children could not study at local grammar schools because the elder Mantell was a follower of the Methodist church and the 12 free schools were reserved for children who had been brought up in the Anglican faith.
A Mantell gyerekek nem tanultak a helyi gimnáziumokban, mivel az idősebb Mantell a metodista egyház követője volt, és a 12 ingyenes iskolát az anglikán hitűek számára tartották fenn.
