Her oldest sibling,
Peadar Kearney, was an ardent republican who wrote the lyrics to the song that would become the Irish national anthem,
"The soldier's song". It was through him that Behan met a printer's compositor and member of the Irish Volunteers, Jack Furlong. They married in 1916. Behan was an active member of
Cumann na mBan, and served as a courier to the
General Post Office, Dublin and other outposts during the
Easter Rising 1916. At the same time, Furlong fought in the Jacob's factory garrison. The couple had two sons:
Roger Casement (‘Rory’) Furlong (1917–1987) and Sean Furlong (born March 1919). Sean was born six month's after Behan was widowed when Furlong died in the
Spanish flu epidemic of 1918. She lived with her mother-in-law, who was also a republican and seamstress who made Irish Volunteer uniforms. She was arrested for running an IRA safe house. She worked for a short time for
Maud Gonne as a housekeeper, where she met
W. B. Yeats and
Sarah Purser. A study painted of Behan by Purser is now in the
National Gallery of Ireland entitled
The sad girl. From 1918 to 1922 she worked as a clerk in the
Dublin Corporation, whilst also a caretaker in the Harcourt Street branch of the White Cross republican aid association. Stephen's mother owned three slum tenements, so the Behans lived rent-free in a one-room basement flat at 14 Russell Street. Owing to her disdain at gossiping on the house steps, she was nicknamed "Lady Behan" by her neighbours. When Stephen's mother died in 1936, the Behans moved to a newly built council house in
Crumlin, living at 70 Kildare Road. The family found the new house far from work and school, and the local area devoid of community. The family experienced extreme poverty frequently, owing to Stephen's unemployment and during the 9 month long building strike of 1936. Despite their circumstances, the house attracted conversation, music, books and politics. The Behan's republican, socialist, labour activist and anti-clericalism had a strong effect on their sons, particularly Brendan and Dominic. Such was the volume of radical meetings that took place at the Behan home, it was dubbed "the Kremlin" by their neighbours, and a "madhouse" by Stephen. During
The Emergency of 1939 to 1945 she fought against local shopkeepers who ignored price controls, and was labelled as "red" for her anti-
Franco and pro-
Stalin sympathies. ==Later life==
