Show ContentsO'Concannyn History, Family Crest & Coats of Arms

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'Concannyn 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

Early Origins of the O'Concannyn family

The surname O'Concannyn 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'Concannyn family

Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name O'Concannyn: 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.



The O'Concannyn Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto Translation: Wisdom without blemish.
