[1] Membership was small in the early days with only a few housing estates in the area and the first set of (second-hand) jerseys was received from a local club in Portadown.
By 1970 six housing estates had been built in Craigavon and Éire Óg's membership and teams grew with the newly developed area.
By early 1973, when Lismore Comprehensive School was established in the community, Éire Óg GFC was fielding teams at all under age levels including U10s and Minors.
[citation needed] During the 1980s the club flourished, and although it was a tumultuous time in Ireland's recent history Éire Óg started to move up the Divisions.In 1977 they experienced their first success when the U14 team won the N. Armagh football league.
Éire Óg has won Armagh and Ulster Scór titles and in 2005 its Irish music instrumental group represented the club at the All-Ireland Scor finals in County Kerry.
In the 1970s the club had erected goal posts in a field between Carrigart and Pinebank housing estates, and in 1979 was in a position to level out and develop this land to a full pitch for its football and camogie teams.
