During the 1920s and 1930s the Unknowns were the dominant football club in Bray, playing in the League of Ireland for nineteen seasons from 1924–25 to 1942–43.
However, in the 1950s, Bray Wanderers emerged as the town's strongest team, enjoying success in both the Leinster Senior League and the FAI Intermediate Cup.
Other teams in this league this season included Shamrock Rovers, Bohemians B, St James's Gate B, Pioneers, Shelbourne United, Midland Athletic, Brooklyn, Merrion, Glasnevin, CYMS and Richmond.
