O'Flynn History, Family Crest & Coats of Arms
Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Flynn originally appeared in Gaelic as O Floinn, which is derived from the word "flann," which means "ruddy."
Early Origins of the O'Flynn family
The surname O'Flynn was first found in Tuitre (now Antrim,) where they were Lords of Tuitre.  However, the O'Flynn surname arose independently in several parts of Ireland. Perhaps the oldest line were a Sept of O Floin in Armagh, Ulster, where they were a senior branch of Clanna Rury of Ulidia, claiming descent from King Colla Uais, the famed 4th century Irish King, who in turn was descended from the Heremon royal line.
The family claim descent from "Flann ("flann:" Irish blood), meaning "the man with the red complexion:" his son; a quo O'Flainn, and the name of the mountain Sliabh-ui-Fhloinn. Feah O'Flynn; his son; the first of the family that assumed the sirname."

To escape the religious and political discrimination they experienced primarily at the hands of the English, thousands of Irish left their homeland in the 19th century. These migrants typically settled in communities throughout the East Coast of North America, but also joined the wagon trains moving out to the Midwest. Ironically, when the American War of Independence began, many Irish settlers took the side of England, and at the war's conclusion moved north to Canada. These United Empire Loyalists, were granted land along the St. Lawrence River and the Niagara Peninsula. Other Irish immigrants settled in Newfoundland, the Ottawa Valley, New Brunswick and Nova Scotia. The greatest influx of Irish immigrants, however, came to North America during the Great Potato Famine of the late 1840s. Thousands left Ireland at this time for North America and Australia. Many of those numbers, however, did not live through the long sea passage. These Irish settlers to North America were immediately put to work building railroads, coal mines, bridges, and canals. Irish settlers made an inestimable contribution to the building of the New World. Early North American immigration records have revealed a number of people bearing the Irish name O'Flynn or a variant listed above, including:
