Carr spends the majority of her childhood in Pallas Lake, County Offaly, adjacent to the town of Tullamore. Her father, Hugh Carr, is a playwright and studies music under Frederick May, while her mother, Maura Eibhlín Breathnach, is the principal of the local school and writes poetry in Irish. It is said that “there were a lot of literary rivalries.” As a child, she and her siblings build a theater in their shed.

She lectures in the English department at Dublin City University in 2016. She is considered one of Ireland’s most prominent playwrights and is a member of Aosdána.
