Ether (1890). Death and legacy MacCullagh was an idealistic nationalist, in the sense of the time. He unsuccessfully contested the election for the Dublin University constituency in 1847. Suffering from overwork and a bout of depression, he died in 1847 by cutting his throat in his rooms at Trinity College Dublin. After his death, Hamilton helped obtain pension for his sisters. In May 2009, an Ulster History Circle plaque was unveiled at his family tomb at St Patrick's Church in Upper Badoney. The plaque was part of events organised by the Glenelly Historical Society to mark his life.
