Lady Charlotte Guest - Wikipedia
Lady Charlotte Guest: (née Bertie) (19 May 1812 – 15 January 1895), later Lady Charlotte Schreiber, was an English translator and business woman. An important figure in the study of Welsh language and literature, she is best known for her pioneering translation from Welsh into English of several medieval tales to which she gave the name Mabinogion. Geraint and Enid served as the basis for Alfred, Lord Tennyson's two poems about Geraint in the Idylls of the King.
