Irish: in Ireland, this is generally the Norman name (see 1 above), established in Meath by Sir William D'Arcy in the 1360s, but it was also adopted for Ó Dorchaidhe ‘descendant of the dark one’, from dorcha ‘dark, gloomy’, a Connacht name that fell together with the Norman surname, which was introduced by Sir William D'Arcy and Sir John D'Arcy, Chief Justiciar of Ireland in the 14th century.
