Gifford was a member of
Inghinidhe na hÉireann, a women's political organisation active from the 1900s. It was founded by
Maud Gonne and a group of working-class and middle-class women to promote Irish culture and help to alleviate the shocking poverty of Dublin and other cities at a time when
Dublin's slums were unfavourably compared with Calcutta's. Gifford, who was already writing under the name "John Brennan" for
Sinn Féin, was asked to write for its newspaper
Bean na h-Éireann. Her articles varied from those highlighting poor treatment of women in the workplace to fashion and gardening columns, some written under the pseudonym Sorcha Ní hAnlúan. She also worked, along with her sisters, in
Maud Gonne's and
Constance Markievicz's dinner system in
St Audoen's Church, providing good solid dinners for children in three
Dublin schools – poor Dublin schoolchildren then often arrived to school without breakfast, went without a meal for the day, and if their father had been given his dinner when they arrived home, might not eat or might only have a crust of bread that night. In 1911 she was elected (as John Brennan) to the executive of the political group
Sinn Féin. Gifford was a member of
Cumann na mBan (The Irish Women's Council) from its foundation in Dublin on 2 April 1914. Its members learned first aid, drilling and signalling and rifle shooting, and served as an unofficial messenger and backup service for the
Irish Volunteers. During the fight for Irish Independence the women carried messages, stored and delivered guns and ran safe houses where men on the run could eat, sleep and pick up supplies. ==United States==
