Cecilia Maria Barthélemon
Born into a musical family (daughter of a French violinist and composer, Francois Hippolyte BarthelŽmon and Mary BarthŽlemon), Cecilia made her debut in London in 1779, performing a vocal duet with her mother. Joseph Haydn was a family friend and listed Cecilia as one of the London musical personalities in his 1792 London Notebook. She in turn dedicated her keyboard Sonata op. 3 to him and was a subscriber to his Creation. Cecilia married Captain E.P. Henslowe, the son of the Navy Commissioner, and appears to have ceased composing after that.
