She was engaged to a Viscayan engineer, but after his death in a mining explosion in the Basque Country, Keating returned to Ireland in May 1916 to live with an aunt in Raheny, Dublin.
Having returned to Dublin, she moved in left-wing republican and feminist circles with Charlotte Despard, Rosamond Jacob, Dorothy Macardle, and Harry Kernoff.
In 1937, she hosted a pro-republican Basque priest, Fr Ramon Laborda during his visit to Ireland, interpreting for him at public meetings organised by the Spanish Aid Committee.
Her activism gained publicity when she sat on the "mother-and-child scheme committee" in 1951, campaigning for the free maternal and infant medical services proposed by the Minister for Health Noël Browne.
[1] The Keatings hosted a wide range of activists, dissidents and radicals in their home throughout the 1950s, as well as often housing and feeding a cohort of struggling poets and artists.
They were regular attendees at Austin Clarke's Sunday salons, and were active in many causes including opposing anti-semitism in Ireland and abroad and supporting the 1960s Irish Anti-Apartheid Movement.
She was an active member of the political discussion group, the 1913 Club, which espoused the socialist nationalism of James Connolly, and was founded by Owen Dudley Edwards, David Thornley and others.
[1] Keating died at her home, 'The Wood', Ballyboden Road, Rathfarnham, on 4 March 1965 of heart failure, and is buried at Cruagh cemetery, Rockbrook, County Dublin.
