It soon adopted the name of Tomás Mac Curtain (1884–1920), in honour of the late Lord Mayor of Cork whom members of the Royal Irish Constabulary (RIC) shot dead during the Irish War of Independence, but the club was often referred to as Forest Gate in the early days.

It was at this time that the club was known as Hibernians, after a dance hall which members attended and a potential sponsor.

In 1955 the newly crowned All-Ireland Senior Hurling Championship winner, Cork (featuring Christy Ring), travelled to Dagenham and played a "Dagenham Select" team, which consisted heavily of McCurtains players.

With the upturn of economic fortunes in Ireland and the emergence of the Celtic Tiger economy, the GAA in London struggled as many Gaels returned home.

Around the turn of the century, the club relocated once more to Goodmayes Hospital Sports Grounds, where it currently resides.
