Together they constitute one of the fifty most common names in Ulster and eighty to ninety per cent of those of the name in Ireland are of that province, principally Antrim, Down and Tyrone. James MacCulloch of Wigtownshire was one of the fifty Scottish undertakers of the Ulster Plantation and in 1610 he was granted 1000 acres in Glenties in Donegal. Though he lost his grant four years later, he and his tenants remained. James MacCullagh, 1809-47, a brilliant mathematician and physicist, was born in Upper Badoney, Co. Tyrone. His suicide at the young age of thirty-eight was thought to have been caused by a fit of madness brought on by overwork. John Edward MacCullagh, 1837-85, who became a famous actor in the USA, was born in Coleraine, Co. Derry.

After a brilliant career at T rinity College, Dublin, he was elected fellow in 5832. From 1832 to 1843 he held the chair of mathematics; and during his tenure of this post he improved in a most marked manner the position of his university as a mathematical centre. In 1843 he was transferred to the chair of natural philosophy. Overwork, mainly on stfbjects beyond the natural range of his powers, induced mental disease; and he died by his own hand in October 1847. SIR WILLIAM MACCORMAC HORATIO MACCULLOCH

McCullough Genealogy General: The McCullough surname is found in both Ireland and Scotland. In addition, there are McCulloughs who came from Scotland and emigrated to Ireland at various times. What this means is that unless you know about your particular ancestor you cannot state whether you have an Irish or Scottish background. In Scotland, the McCulloughs were allied with a number of larger clans, primarily the MacDougalls, the Rosses, and the Munros. To a lesser degree there were also some who allied with MacDonald of Sleat and with Gunn (MacCullie). Rather than paraphrase, I will quote a little more details from three authoritative sources: Ireland: The Surnames of Ireland " by Edward MacLysaght "MacCullagh, -Collough Mac Cu' Uladh or Mac Con Uladh (hound of Ulster). A numerous name in Ulster. Also, as MacCulloch, Scottish. See MacColla and MacCullow" The Book of Ulster Surnames " by Robert Bell "MacCullough (also Cully, MacCullagh and MacCully) Taken together the origins of these native Ulster and Scottish Planter names are a little complicated. MacCullough and MacCullagh together constitute one of the fifty most common names in Ulster and 80 per cent of those names in Ireland are of that provence. The names are most numerous in counties Antrim, Tyronne, and Down. The Ulster Galic names Mac Cu' Uladh or Mac Con Uladh, both meaning 'son of the hound of Ulster', were anglicised as MacCullagh. (The name also gave rise to Coloe, Coloo, MacAnaul, MacAnulla, MacNaul and MacNully, but see also MacNally.) In Petty's 'census' of 1659 MacCullough was listed as one of the 'principal Irish names' in the Co. Antrim baronies of Antrim, Belfast, Carrickfergus and Toome and also in the barony of Lower Iveagh in Down. However, many of these must have been Scottish. By the mid-nineteenth century the name in Co. Antrim was concentrated in the east of the barony of Lower Antrim.

Back to table of contents. JAMES MAC CULLAGH The other outstanding mathematician in Trinity at the same time as Hamilton was James Mac Cullagh, who was appointed professor of mathematics in 1835 and later transferred to the chair of natural philosophy in succession to Humphrey Lloyd. Mac Cullagh is best known for his researches in optics, and particularly for his model of the aether. Mac Cullagh's work on light propagation was much admired. It brought him the Copley medal of the Royal Society and the Cunningham medal from the Royal Irish Academy. His achievement reflected on the one hand a strong physical intuition and deep understanding of the phenomena, and on the other a remarkable mathematical talent. Mac Cullagh's real skill was as a geometer: as an effective and inspiring teacher he influenced a generation of students who in turn maintained the emphasis on geometry within the school. He was critical of his fellow countrymen for what he saw as their lack of pride in their own country; their lack of interest in their own past, or of care for the sites and artefacts associated with that past. In a characteristically noble gesture he paid what must have been a large part of his life savings to buy the Cross of Cong, a magnificent twelth century processional cross, when this came on the market and presented it to the Royal Irish Academy in the hope that this would be the start of a major national collection, as indeed was the case.
