Muriel St. Clare Byrne, born in 1895 [1], was a prominent historical researcher, specializing in the reign of Henry VIII of England. She gathered together and edited primary sources and published these, including the Lisle Letters, and the Letters and Papers of the Reign of Henry VIII, as well as publishing books which were entirely her own work, such as Elizabethan Life in Town and Country, Elizabethan Home and Common or Garden Child. A not-unfaithful record.[2] A friend of Dorothy L. Sayers, she co-wrote the play upon which Sayers's novel Busman's Honeymoon was later based.
