Hundreds of years ago, the Gaelic name used by the McKeigyn 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 McKeigyn family

The surname McKeigyn 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 McKeigyn family

Ireland became inhospitable for many native Irish families in the 19th centuries. Poverty, lack of opportunities, high rents, and discrimination forced thousands to leave the island for North America. The largest exodus of Irish settlers occurred with the Great Potato Famine of the late 1840s. For these immigrants the journey to British North America and the United States was long and dangerous and many did not live to see the shores of those new lands. Those who did make it were essential to the development of what would become two of the wealthiest and most powerful nations of the world. These Irish immigrants were not only important for peopling the new settlements and cities, they also provided the manpower needed for the many industrial and agricultural projects so essential to these growing nations. Immigration and passenger lists have documented the arrival of various people bearing the name McKeigyn to North America: Rev. Michael Egan who became Bishop of Philadelphia in 1790. Many other Egans settled in this city during the 19th century.



The McKeigyn 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.
