Larry Lardner, a native of Athenry, County Galway, was a Brigade Commandant for the Irish Republican Army in his locality.
He was by trade a publican and a member of the Irish Republican Brotherhood (IRB) Supreme Council for Connacht in 1917.
[citation needed] He, along with Liam Mellows and Pádraig Ó Fathaigh, travelled to Limerick where they were informed by Patrick Pearse at an IRB meeting that a rebellion would take place at Easter 1916.
[citation needed] Following Ó Fathaigh's arrest, Lardner and Mellows led some hundreds of local men in occupying Moyode Castle on 26 April.
Early in January 1920, he was part of a group of local men (including Bill Freaney) who approached Frank Shawe-Taylor on behalf of some local people who were requesting a road to travel to Mass.
