Enriqueta Augustina Rylands

Enriqueta Augustina Rylands (31 May 1843 – 4 February 1908) was the founder of the John Rylands Library, Manchester.

Born in Havana, Cuba, she was one of five children including José Esteban (later Stephen Joseph, who was her twin brother), Blanca Catalina and Leocadia Fernanda. Her father was Stephen Cattley Tennant (1800–1848), a merchant, and her mother, Juana Camila Dalcour (1818–1855).

Tennant retired to Liverpool, but died within a year. His widow migrated to Paris and married pianist and polymath Julian Fontana. Juana and Julian had one son, Enriqueta's half brother, Julian (Jules) Camillo Adam Fontana, who was born in 1853. Enriqueta Tennant was raised a Roman Catholic and completed her education in New York, London and Paris. In later life she abandoned Catholicism and became a Congregationalist, under the influence of the Rev. Thomas Raffles (1788–1863).
