St Stephen's Green,
Dublin,
Ireland, the daughter of John Gunn, the director of the
Gaiety Theatre, and Hilda Killock. She married English actor
Leslie Henson in 1926. In 1932, she appeared in the premiere of
Noël Coward's
Design for Living on Broadway, appearing in several other London and Broadway shows, including Coward's
Set to Music (1939). After her divorce from Henson, she appeared in numerous well-known post-war films, often alongside
Jack Warner, whose wife she played in
Train of Events,
The Captive Heart and
The Blue Lamp; the scene in the latter in which her character learns of her husband's death has been described as "a masterpiece of understated emotion, moving without falling into sentimentality."{{cite web |url=http://www.screenonline.org.uk/film/id/447704/ She died in London on 21 December 1982 aged 85. ==Partial filmography==
