MacCarthy MacCarthy MacCarthy (Irish: Mac Cárthaigh), also spelled Macarthy, McCarthy or McCarty, is a Gaelic Irish clan originating from Munster, an area they ruled during the Middle Ages. It was and continues to be divided into several great branches. The MacCarthy Reagh, MacCarthy of Muskerry, and MacCarthy of Duhallow dynasties were the three most important of these, after the central or MacCarthy Mór line. Their name, meaning "son of Cárthach" (whose name meant "loving"), is a common surname that originated in Ireland. As a surname, its prevalent spelling in the English language is McCarthy. Several variants are found, such as McCarty
Scottish Gaelic name MacKonochie, MacOnachie, MacOnechy, MacOnochie, Donohue" or "Donohoe" (ignoring the Mac/Mc variation).
