Adams's maternal great-grandfather, Michael Hannaway, was also a member of the IRB during its bombing campaign in England in the 1860s and 1870s. Michael's son, Billy, was election agent for Éamon de Valera at the 1918 Irish general election in West Belfast. Adams attended St Finian's Primary School on Falls Road, where he was taught by La Salle brothers. Having passed the eleven-plus exam in 1960, he attended St Mary's Christian Brothers Grammar School. He left St Mary's with six O-levels and became a bartender. He was increasingly involved in the Irish republican movement, joining Sinn Féin and Fianna Éireann in 1964, after being radicalised by the Divis Street riots during that year's general election campaign.
