Early Origins of the O'Mulvany family

The surname O'Mulvany was first found in County Derry, where they were hereditary ollavs of O'Cahan (O'Kane.) One of the first records of the name was Ó Maiol Mheanna mentioned in the Annals of Ulster in 1164 where the family claim descent for the from Eoghan, son of Niall of the None Hostages and was probably associated with the river Meana which flowed into Lough Neagh at Randalstown. 1

Another source claims that the name claims descent from the Donnelly line from MaolfIona which meant in English "the devotee of wine" 2

As both authors referenced were Chief Heralds of Ireland, we must leave it up the reader to decide who is more accurate.

"O'Mulvey was a Chief in the Barony of Mohill, County Leitrim, in which county about 50 per cent, of persons bearing the name Mulvey are now found." 3

Migration of the O'Mulvany family

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name O'Mulvany or a variant listed above: John Mulvay, who settled in Philadelphia in 1746; Patrick Mulvany, who arrived in Philadelphia in 1808; James Mulvany, who arrived in Baltimore in 1809.
