Notable players
Michael Donnellan was a talented footballer and won an All-Ireland medal with the Galway Senior football team in 1925. He died in Croke Park at the 1964 All-Ireland final, shortly before his son, John Donnellan, as victorious Galway captain, received the Sam Maguire Cup. John would follow in his father's footsteps in both football and political pursuits. He captained the Galway winning team in 1964, the first of a historic "3 In A Row". His brother, Patrick was also on the team.
John's son Michael, kept the family tradition alive by winning two All-Ireland titles in 1998 and 2001. He was one of the most exciting players of his time but he never enjoyed similar success with Dunmore. Armagh footballing great Oisín McConville once said of him "He was the best athlete I've ever played against". His capabilities were never more evident than in the All-Ireland final of 1998 where his surging runs and skilful ball-carrying were crucial to the team's victory. His stunning run of the full length of the pitch to assist Seán Óg de Paor was voted the best moment in the history of GAA. He later moved to Salthill-Knocknacarra in 2003 and won an All-Ireland club medal in 2006.
