Gaelic, otherwise known as Early Modern Irish, was used in Ireland from around the year 1200 until the 18th century. It is from this language that we found the first references to the name O'Concanyn as Ó Concheanainn, possibly meaning "fair headed hound." 1

The family descends from Cuceannan, who was killed in 991. Another reference, claims that the surname could have been derived from MacConceannain, and in this case it was derived from the Irish "conn," a man's personal name + "gan," which means without + "an," which means a "lie," collectively meaning "Conn the speaker of truth." 2

The surname O'Concanyn was first found in Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, and Roscommon where they claim descent from the Heremon kings, from the Ui Bruin and more specifically they were derived from Dermot, brother of Murias the 29th King of Connacht who was alive in the 9th century. They claim descendancy from the O'Connors, hence the similarity of the Coat of Arms which both depict a tree at the center point.

Migration of the O'Concanyn 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'Concanyn or a variant listed above: Patrick Cancannon arrived in New York State in 1811; Michael Concannon who arrived in Philadelphia in 1878; Edward, George, James, Michael, Timothy, arrived in Philadelphia or Boston between 1840 or 1870.
