She resided in a second-class cottage in the townland of Murphystown in Sandyford with her parents, brothers James and Michael J. and sister Margaret.

[2][3] When she was 11 years old Gill’s older sister Jane Gill left their family home in Murphystown to work with Susan Mary "Lily" and Elizabeth "Lolly" Yeats, of the well-known Irish arts and literary Yeats family, in Dun Emer Industries, which would later be known as the Cuala Press.

[1][6] Her active involvement in the Crokes and Inghinidhe na hÉireann encouraged her to expand her knowledge of Irish culture, literature, history and art as well as the language itself.

She took the anti-treaty side during the Civil War, and was arrested in May 1923 alongside the secretary of the Camogie Association, Áine Ní Riain, and was interned in Kilmainham for several months.

[9] She joined Crokes football and hurling club where Harry Boland was a member and marched with the Dublin camogie delegation to the funeral of Jeremiah O'Donovan Rossa.
