"Material relating to the Gaelic Union, consisting of correspondence, membership card and scrap-books. The Gaelic Union (Aondacht na Gaeilge) founded in March 1880 by a group of Irish-language activists and scholars who had previously been members of the Society for the Preservation of the Irish Language, including David Comyn, Thomas O'Neill Russell and Canon Ulick Bourke. Dissatisfied with what they considered the lack of activity and public impact by the earlier society, they sought to implement practical measures that would arrest the decline of Irish as a living language.
