Etymology of Keagan

What does the name Keagan mean?

Hundreds of years ago, the Gaelic name used by the Keagan family in Ireland was Mac Aodhagain, which means "son of Aodh, son of fire," a personal name usually Anglicized as Hugh. A Brehon family originally of Uí Maine, which settled in Ormond. 1

The family claim descent from Saint and Bishop Eoghan (d. 618), "of Ardsratha, now Ardstraw, in the county of Tyrone and diocese of Derry. Descended from Ugaine Mor on the father's side he was thus connected by kindred with the chieftains of Leinster, while through his mother, Muindech, he claimed relationship with the Ulster families." 2

Another source confirms the name descends from "the cineal Eoghain, [who] were the ' genus' or progeny of Eoghan, a great Irish chief contemporary with St. Patrick. The name is Anglicized to Owen and Eugene. " 3

Early Origins of the Keagan family

The surname Keagan was first found in County Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster, where they held a family seat from very ancient times.

The ancient Egans were lawyers of Ui Maine, a region which is today called Galway, Roscommon and Offaly. The earliest surviving Irish law manuscript, In Senchas Már, was written prior to 1350 at a school (patronized by Mac Aodhagain) at Duniry, near Loughrea.

Migration of the Keagan family

Death and immigration greatly reduced Ireland's population in the 19th century. For the native Irish people poverty, hunger, and racial prejudice was common. Therefore, thousands left their homeland to seek opportunity in North America. Those who survived the journey and the quarantine camps to which they arrived, were instrumental towards building the strong developing nations of the United States and the future Canada. By far, the largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. These were employed as construction or factory workers. An examination of passenger and immigration lists has shown early immigrants bearing the name Keagan: Rev. Michael Egan who became Bishop of Philadelphia in 1790. Many other Egans settled in this city during the 19th century.

The Keagan 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: Fortitudine et prudentia
Motto Translation: With fortitude and prudence.
