Neva Carr Glyn or Neva Carr Glynn (born Neva Josephine Mary Carr Glyn, 10 May 1908 – 10 August 1975) was an Australian contralto and actress born in Melbourne to Arthur Benjamin Carr Glyn (died 16 January 1923), a humorous baritone and stage manager born in Ireland, and Marie Carr Glyn (late Mola), née Marie Dunoon Senior (10 June 1874 – 24 December 1953), an actress with the stage name "Marie Avis". She had one half-sister Gwendoline Arnold O'Neill and two half-brothers Sacheverill Arnold Mola and Rupert Arnold Mola. She was named "Neva" for a great-aunt, who was a contralto of some quality. Both spellings of her surname appear in print roughly equally and apparently arbitrarily.
Neva was born while her parents were with the Fred Niblo company touring the J. C. Williamson circuit. Her theatrical debut was four months later, in New Zealand, when Fred Niblo carried her on stage. She was playing the young William to her mother's Lady Isabel Vane in East Lynne at the age of four. From age five to twelve, when her father died, she was a boarder in various convent schools, ending in Sydney. At eight she was enrolled in the Minnie Hooper School of Dancing and at eleven she was dancing in a revue The Queen of Sheba at the Sydney Town Hall. At thirteen her dancing skills won her a place in the chorus line of a Fuller Brothers pantomime Dick Wittington and His Cat at the Majestic Theatre, Newtown then in 1925 toured with the Band Box Revue. For the following six years she worked for them under contract, touring Australia and New Zealand in revues. Robinson Crusoe from 1925–26 as Principal Girl, "Aladdin" 1927–28 as Principal Boy and Clowns in Clover for the Frank Neil company are noted appearances, this last starring Roy Rene. Other stars she worked with at this time were Jim Gerald and George Wallace.
In 1929 she and her mother joined the Frank Neil company in a tour of South Africa playing leads in such comedies as Up in Mabel's Room, from where she travelled to London in 1931 and got a break with the Firth Shephard company playing the Sigmund Romberg operetta Nina Rosa (produced by Carol Reed) then with Firth Shephard and Leslie Henson in a string of "Aldwych comedies" such as Living Dangerously (1934), Accidentally Yours (1935), and Aren't Men Beasts? in 1936. She also appeared in four movies including Girls Please (1934) with Sydney Howard and The Squeaker (1937) with Ann Todd.
