Originally Mac Mathghamha, but in contemporary Irish, Mac Mathúna, is one of the best known and distinguished surnames in Ireland. It has to be said that some Mahons may be really MacMahons who simply dropped the prefix. However, as we will see later, most Mahons are of different stock. The name is patronymic in nature, from the personal name Mathghamhuin, which itself is taken from an old Irish word for a bear. There are two distinct septs of MacMahon, each descended from a different Mahon. (cite3)
The first of these is the sept of MacMahon of Thomond, whose territory, Corcabaskin, was adjacent to the O Briens of Thomond in County Clare and indeed they are "cousins" to the O'Briens, being descended from Mahon who was the son of Murtagh Mor, an O Brien king of Ireland who died in AD 119. The Corcabaskin MacMahons' last chieftain died after the battle of Kinsale, accidentally killed by his own son. Also at Kinsale was Brian MacMahon, who turned traitor and informed the enemy of the Irish plans of attack. (cite3)
This is an Irish tower castle from 16th century. It overlooks the Doonbeg River which flows into the bay of Dunmore on the Atlantic Irish coast.
The castle is about seventy feet high. A spiral staircase which leads to the top commands a great view. Two families of Country Clare are related to this tower house - the clan MacMahon and the clan O'Brien.
The genealogy of clan MacMahon and the O'Brein family shows that they have a common Irish ancestor - Mahon, son of Murtagh Mor who was a grandson of Brian Boru. Brian Boru, High King of Ireland, descended from Cennedig of the royal clans of Munster.
Dun Beag - the small fort
Doonbeg Castle was originally built for Daniel O'Brien, the Earl of Thomond. Turlough MacMahon of West Clare took Doonbeg in 1585. Some 10 years later, 1595, O'Brien reclaimed Doonbeg...
The Annals of the Four Masters records: M1595.21 (cite4) Turlough, the son of Brian, son of Donough, son of Donough Bacagh Mac Mahon, Lord of West Corca-Bhaiscinn, a man of great fame and character throughout Ireland, considering his patrimony, for he had but one cantred, passed; and his son, Teige Caech, took his place.
Tadhg (Teige - the one eyed Lord) rebelled against the English and their supporters. The Earl of Thomond sent his brother, Henry O’Brien, to talk reason with his relative. But Teige was gone and Henry took up with his daughter. When he finally returned several weeks later there was a battle but Henry escaped. Queen Elizabeth at this time declared McMahon a rebel and granted his entire estate to Daniel O'Brien, which included Doonbeg.
In 1619 Daniel O'Brien gave Doonbeg Castle to James Comyn. The Crown took possession of it in 1688 and it was sold in 1703.
By the late 1800's the Castle of Doonbeg had fallen into disrepair, like so many other Irish castles. Several local families lived on the different floors of Doonbeg Castle until the 1930's.
- "You have heard in song and story of the beauties of all lands,
- Of their hills and dales and mountains,
- and their rivers, lakes and strands,
- But of all those wondrous places you can read of, hear and see,
- There are none of them to rival Old Doonbeg by the sea."
