The area known as Tullyhunco in County Cavan was historically known as the Lordship of Tullyhunco, ruled by the MacTiernan family until the 1600s.

MacTiernan: Where does the name MacTiernan come from?
The surname MacTiernan is of Irish origin, derived from the Gaelic "Mac Tighearnain," which means "son of Tighearnan." The name Tighearnan itself originates from the Gaelic word "tighearna," meaning "lord" or "master.” Hence, the name can be translated as "son of the lord or the master." The MacTiernan family were traditional Gaelic Irish lords in the kingdom of Breifne, which is predominantly in the modern county of Cavan, but also parts of Southern County Fermanagh in Northern Ireland.
Today, MacTiernan, along with its various spelling variants such as Tiernan, McTiernan, and McKiernan, is predominantly found in Ireland, especially in the North Connacht region and the counties of Leitrim and Sligo. Some descendants eventually migrated to other English-speaking countries like the United States, Canada, Australia, and the United Kingdom due to historical circumstances such as the Great Famine or in pursuit of better opportunities, making the name fairly common in these countries as well. However, it remains less common globally compared to other Irish surnames.
Variations of the surname MacTiernan

It's also worth noting that these names can also interchangeably use 'Mac' or 'Mc' based on individual family preferences.
