Mary Barton, a pioneer of fertility treatment, thought her husband was perfect. And doesn’t every child deserve the perfect father? So Mary used her husband’s sperm to impregnate up to a thousand women, and then burnt all the records. A thousand resulting children, the 'Barton Brood', with no idea about their shared father. Meeting each other. Making friends. Having babies.Maud Dromgoole’s play Mary's Babies is based on the true story of Mary Barton and the Barton Brood, researched through surveys and interviews. Provocative, funny, and fascinating, it imagines a series of encounters between these unknowing half-siblings.Mary's Babies premiered at Jermyn Street Theatre, London, in March 2019.
