The McCarthy coat of arms

The name appears as 'MA CARTY' in the 'List of Names of Irish Septs as given in the Book of Arms, compiled by Sir James Terry, Athlone Herald (1690)', as printed by Matheson. The list gives sept names only; it does not describe any arms, and it does not mean that everyone named McCarthy is entitled to a coat of arms.[5]

The design shown is a coat of arms associated with the McCarthy surname. In Irish and British heraldry a coat of arms is granted to one person and passes to their heirs; it does not belong to everyone who shares the surname. Many families still use the arms of their name as a symbol of their heritage.

What does the surname McCarthy mean?

Woulfe gives McCarthy as an anglicised form of Mac Cárthaigh, 'son of Cárthach', from the Old Celtic Caratacos, 'loving', an ancient Irish personal name.[1]

Where in Ireland is McCarthy from?

Munster. Woulfe says the MacCarthys were Kings of Desmond (South Munster) and, after the Anglo-Norman invasion, settled in Cork and Kerry. In 1890 more than half of McCarthy births were in Cork, followed by Kerry and Limerick.[1][4]

What were the main branches of the MacCarthys?

Woulfe names three great branches: MacCarthy More, who lived chiefly in Kerry; MacCarthy Reagh, lord of Carbery in West Cork; and MacCarthy of Muskerry, with numerous minor branches.[1]

How common is McCarthy in Ireland?

In Matheson's survey of the 1890 Births Index, McCarthy was 13th of the hundred principal surnames, with an estimated 22,300 people.[3]

Is every McCarthy descended from the Kings of Desmond?

The sources do not say so. Woulfe also prints '(MacCarthy, MacCaffry)', in brackets, among the anglicised forms of a different surname, Mac Eachmharcaigh, 'son of Eachmharcach', which he calls a Donegal surname.[1][2]
