This Club changed it's name to 'Deel Rovers' in 1906 having been called 'Crossmolina Dr Crokes GAA Club' since it was founded in 1887. The officers were chairman Fr Eddie Doherty, CC secretary Pat Rowland; Treasurer Willie Joe Tolan.

The following year, with Tom Rochford as captain, they won the County title, defeating The Neale in the Final.
Changing from Senior to Intermediate status in 1967 brought little success and the Club regraded back to Junior in 1972. Three years later, with Christy Commons as captain, they won the County Junior title, defeating Ballintubber in the Final.
They were defeated in the North Mayo Finals of 1984, 1985 and 1995 but won the North Mayo title in 1997, with Aiden Heffernan as captain, defeating Ardagh in the Final and again in 1999, with Peader Flynn as captain, defeating Belmullet.

They won their third title by defeating Ballina in 1999 and defeated Roscommon Gaels, after a replay, to win their first Connacht Club title. They won the Senior league title for four years in succession in 1996, '97, '98, '99. The most historic victory for the Club was of course winning the All-Ireland Club Final in 2000.
