1872 – Mícheál Ó Lócháin wrote letters to The Irish World, an Irish-American journal, about "the necessity of preserving the Irish language in order to preserve Irish nationality" and recommending that classes and societies be founded to accomplish this. In that same year he established a "Philo-Celtic" Irish language class for adults at the school in Brooklyn where he taught.
1881 – Ó Lócháin founded AN GAODHAL (official magazine of the Brooklyn Philo-Celtic Society at that time). Its goal was "the language of Ireland to protect, to revive, and to use amongst the Children of the Gaeil."
1882 – Ó Lócháin published this on the cover of the magazine: "The Gaodhal, a Monthly Journal devoted to the Preservation and Cultivation of the Irish Language and the Self-Rule of the Irish Race."
1884 - The goal for the Brooklyn Philo-Celtic Society: "This society shall have for its object the preservation and extension of the Irish as a spoken language."
1886 - Scríobh Ó Lócháin, " 'An Gaodhal' was not founded to do a minute study on the language itself but to broadcast and protect the language."
1896 - Discussing the Irish language movement in America (which he started in 1872), Ó Lócháin said: ".... the object of the Gaelic movement is - and has been - the revival and the reintroduction of the Gaelic as the spoken language of Ireland with English as an accompaniement."
