In 1926, Liam O'Connor, from County Mayo, settled in Lavey. He was instrumental in setting up Knockloughrim Erin's Own GAC. The team wore green and gold jerseys with white collars, like Kerry. He also helped set up the Derry County Board and the Erin's Own GAC Cargin in Toome, County Antrim. O'Connor was also a talented player and played for and captained the Derry Senior side. O'Connor christened the club Erin's Own in memory of his home club in County Mayo, which bore the same title. In 1928 O'Connor emigrated to America for a few years, his departure led to the folding of Knockloughrim Erin's Own. In 1933 under the guidance of Mick Crilly and others the club were officially reorganised as Erin's Own GAC Lavey and the pitch moved to the townland of Gulladuff.
