Coat of Arms of MacMahon of Clare/Thomond

McMahon or MacMahon (UK: /məkˈmɑːn/,[1] US: /məkˈmæn, -ˈmən, -ˈmɑːn/; older Irish orthography: Mac Mathghamhna; reformed Irish orthography: Mac Mathúna) is an Irish surname. The surname arose separately in two areas: in west County Clare and in County Monaghan. Two twin-brothers had a short feud over their fathers title of Marquis which eventually led to the splitting of his land and the brothers separately living in their new found counties. As a result of this, the County Monaghan (Airgíalla) MacMahons are not related to the County Clare (Thomond) MacMahons. McMahone was one of the four sons of Mathghamhna, who then later became known as "The Four Descendants".

HistoryEdit

The first McMahon was given the title of Marquis by his father Mathghamhna, along with his 3 brothers who were also given titles. McMahon is the 2nd son of Mathghamhna and had a rivalry relationship with his much younger brother O'Mathuna (who later anglicized his name to "Mahoney"), which may be due to his younger sibling receiving an Earldom by their father. No records are found of any sort relationship with his younger brother Mahone, who he may have seen as a mere sibling. Nevertheless, McMahone had an excellent relationship with his older brother O'mahony, who was given the title of Duke.

ThomondEdit

The Thomond MacMahons were part of the great tribal grouping, the Dál gCais, and claimed descent from Mahon O'Brien, son of Muirchertach Ua Briain, High King of Ireland.[2] Corcu Baiscin was held by the descendants of Carbry Bascain until the 11th Century, when the descendants of Mahon O’Brien conquered them.[3] Two ruling branches of the clan became firmly established in Corcabaskin, West Clare, where their once strongholds, Carrigaholt Castle and Clonderlaw Castle, are prominent landmarks and a source of local interest today.[4] The last chief of the name was killed at the battle of Kinsale in 1602, and the chiefly line became extinct.

After the defeats of the native Irish in 17th century, many of the Clare MacMahons emigrated to serve in the Irish Brigade of the French Army.

Patrice de MacMahon (1808–1893), was created Duke of Magenta, became a field marshal and later the French president. The MacMahon family are still prominent in France; the family home is the Château de Sully outside Dijon.[5]

OrielEdit

The Oriel (Anglicisation of Airgíalla) MacMahons were based in the barony of Truagh in the north of County Monaghan and ruled the kingdom of Oriel between the thirteenth and the sixteenth centuries. Their last chief, Hugh Oge MacMahon, who had become a lieutenant-colonel in the Spanish army, was beheaded by the English in 1641. A separate McMahon family in County Fermanagh is descended from Mahon Maguire, a grandson of Donn Carrach Maguire. Today, although widespread throughout Ireland, MacMahon remains most common in the two ancestral homelands of Counties Clare and Monaghan.[6]

John O'Hart notes that the MacMahons (sometimes there O'Mahons) were earlier chiefs of the over-kingdom of Ulaid, which then bordered Airgíalla.[7]
