Rose Boote, later 4th Marchioness of Headfort (1878-1958) was a Gaiety Girl  who sang the part of Maisie 'The Messenger Boy' in 1900 under her professional name of Miss Rosie Boote.  It is said that she so charmed the young Marquess of Headfort, Geoffrey Thomas Taylour (1878–1943) that he married her on 11th April 1901. 
'Gaiety Girls' was the name given to the chorus line girls who sang in musical comedy spectacles, at the Gaiety Theatre on the Strand, London.  Rosie was a leading actress and protégée of George Edwards, who from the 1890s managed and produced the shows.  The 'Gaiety Girls' appeared on stage in bathing attire and in the latest fashions. They were respectable, elegant young ladies, unlike the corseted actresses from London's earlier musical burlesques.
The marriage was supposed to have surprised and intrigued Edwardian society, and took place overcoming opposition from the family and even Queen Victoria herself was even said to have commented on the match.  The Marquess was from one of the most prominent Protestant families in Ireland and she a Catholic. Rosie Boote married one of the most eligible young men of her day.  Upon her marriage, she left the theatre and resided with her husband at Headfort house in Ireland and in London, they had a wide circle of friends and entertained such notable guests artists, including Sir William Orpen, playwrites and intellectuals.
