The original Gaelic versions of today's Irish names demonstrate a proud, ancient past. The original Gaelic form of the name McTiernan is Mac Tighearnain, which is derived from the word tighearna, which means "lord."

Early Origins of the McTiernan family

The surname McTiernan was first found in County Cavan, at Tullyhunco where the "Annals of the Four Masters" show no fewer than 33 Tiernans. Almost all were Chiefs of Teallach Donnchadha. Despite their high ranking, their exploits were not well documented from 1250-1550. One must presume that they ruled with compassion and understanding and were amiable to their fellow man. The "Mac" prefix of the name is typically spelt "MacTernan" or "McTernan" and is usually found in the Cavan-Leitrim area of Ireland.

Ternan or Terrenan (d. 431?), was Archbishop of the Picts. "According to his legend he went to Rome, where he spent seven years under the care of the pope, was appointed archbishop of the Picts, and returned to Scotland with the usual accompaniment of miraculous adventures. He died and was buried at Banchory on the river Dee, which was named from him Banchory Ternan. His day in the calendar is 12 June, and the years given for his death vary from 431 to 455. " 1

Among the many spelling variations of the surname McTiernan that are preserved in archival documents are Tiernan, Tierman, Ternan, Kiernan and others.

United States McTiernan migration to the United States +

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 McTiernan:
