History

The name Flynn in Ireland is among the fifty most frequently found in the country. The Irish for this surname is Ó’Floinn and derives from the adjective flann, meaning ‘bright red’, ‘reddish’ or ‘ruddy’, which was originally given as a nickname to one having a reddish complexion.flynn crest

It is one of those which arose independently in several parts of the country and, as might be expected, is widely distributed. It became extremely popular as a personal name in early Ireland and several branches of this clan held independent settlements in various parts of the country. It ranks forty-first in the list of most numerous surnames in Ireland with an estimated total of thirteen thousand persons.

These are found chiefly in two main areas – Cork and Waterford in the south, and on the borders of Connacht and Ulster in the adjacent counties of Roscommon, Leitrim and Cavan.

Two of the O’Flynn septs originated in Co. Cork. Of these O’Flynn of Ardagh Castel (between Skibbereen and Baltimore) was a branch of the Corca Laoidhe; and the O’Flynns of Muskerry were lords of Muskerrylinn (Muscraidhe Ui Fhloinn), i.e. the country between Ballyvourney and Blarney.

They were pushed thence by the MacCarthys and moved to a more easterly location. The most important of the Connacht septs of the name was O’Flynn of Kiltullagh and Kilkeevin in Co. Roscommon.

In the same county O’Flynns were erenaghs of the Church of St. Dachonna near Boyle. The head of the family had the peculiar privilege of mounting the same steed as the royal O’Connor.

Further west at Errew on the shore of Lough Conn was another erenagh family of O’Flynn. Another sept of ÓFloinn was at one time famous in Ulster. The possessed a territory in southern Armagh between Lough Neagh and the sea were the senior branch of Clanna Rury of Ulidia, tracing their descent back to Colla Uais, King of Ireland in the fourth century. The F of Ó Floinn was aspirated in modern Ulster Irish, with the result that the name became Ó Loinn and the anglicized from O’Lynn in the north.

Numerous though they are and were, few O’Flynns have found a place in the pages of Irish history. Fiacha O’Flynn (also called MacFlynn), Archibishop of Tuam was the emissary of the Irish Church to England in 1255. Among the Irish in France, however, they have been prominent both as ecclesiastics and as officers of the Irish Brigade. In modern times Rev. Jeremiah O’Flynn (1788-1831) was a Franciscan friar whose interesting and stormy career relates chiefly to the early church in Australia and later in the USA. Edmund James Flynn (b. 1847) was Premier of Quebec and William James Flynn (1867-1928) was a famous American Detective.

Of the O’Lynns the most noteworthy was Father Donough O’Lynn, O.P., who was martyred in 1608 at the age of 90. “Father O’Flynn”, of the ever populr song, was a fictitious character. The northern form of the name is also popularized in a well know Irish song, “Brian O’Lynn.” John Flynn (1880-1951) Presbyterian missionary (with an Irish Catholic background) is regarded by the Australians of all creeds as one of the finest men their country has produced. He founded the Flying Doctor Service and was known as “Flynn of the Inland.”
