Mcdermott Family History
Mcdermott Name Meaning
Irish: Anglicized form of Gaelic Mac Diarmada ‘son of Diarmaid’ a personal name that may be based on di- + farmat ‘envy’ hence meaning ‘free from envy’. The name Diarmaid was borne in Celtic legend by the lover of Gráinne and in historical times by Diarmaid Mac Murchadha the 12th-century king of Leinster whose appeal to the English for support led directly to the Anglo-Norman presence in Ireland. Compare the Scottish form McDiarmid . There has been confusion with Ó Duibhdhiorma see Dearman .
