Sean Heuston: Born in Dublin in 1881. Along with Con Colbert, Heuston was involved in the education of schoolboys at Scoil Eanna, organising drill and musketry exercises. At the age of 16 he worked at Kingsbridge Railway, which is now named in his honour as Heuston Station. It was here he became the breadwinner for his family as his father was living in London.

A section of the First Battalion of the Volunteers under Heuston commandeered the Mendicity Institute on the south of the Liffey, holding out for two days. He was executed on 8 May 1916.
