O'Mulcahey History, Family Crest & Coats of Arms
- Origins Available:
There are multitude of rich histories underlying the many Irish surnames in use today. The name O'Mulcahey originally appeared in Gaelic as O Maolchathaigh, which means "a descendant of a devotee of St. Cathach." The surname is not, as is often believed, derived from "cathach," meaning "warlike."
Early Origins of the O'Mulcahey family
The surname O'Mulcahey was first found in County Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster.  They claim descendancy from the Moores, hence the same shield. "John, a younger brother or Roger Caoch who is No. 114 on the 'Moore' pedigree, was the ancestor of Mulcahy." The author continues with a footnote, "From a similarity in the pronunciation of the names, some were of opinion the Maolcaich, who is mentioned in the Stowe Missal, might have been the ancestor of the family. "  From these early beginnings, two additional branches were established in Ardpaddeen and in Kilkenny. Of this latter branch, "the ancient fort or rath in the parish of Castleconor, County Sligo known as Rath Maoilcatha, has suggested the idea that this family may have derived their name from the Maolcatha after whom the rath is called; and therefore that they are descended from the royal stock from which branched the O'Connors, Kings of Connaught."

Consequently, in the Middle Ages many people were recorded under different spellings each time their name was written down. Research into the O'Mulcahey family history revealed numerous spelling variations of the name, including Mulcahey, O'Mulcahey, Mulcahy, O'Mulcahy, Mulcahee, Mulkey, McMulkey and many more.

Migration of the O'Mulcahey family
The 19th century brought a massive reduction in Ireland's population. It seemed that during the Great Potato Famine of the late 1840s the Irish people had two options: starve or immigrate. Those that chose the later frequently headed for the United States, hopeful for land, work, and equality. Those determined for free land joined the migration west; while others stayed behind to live in urban centers and often work in factories. Still others began a transitory life in work camps, building the bridges, canals, railways, and highways so critical to the rapidly development of the growing industrial nation. Early passenger and immigration lists have shown many early immigrants bearing the name O'Mulcahey: John and Mary Mulcahy settled in Boston in 1849; along with Patrick; David, Denis, John, Thomas, Timothy, William Mulcahy all arrived in Pennsylvania between 1800 and 1860..
