GREGORY HAYES

Via Latin Gregorius from the post-classical Greek name Gregōrios ‘watchful’ (a derivative of gregōrein ‘to watch, be vigilant’). The name was a very popular one among the early Christians, who were mindful of the injunction ‘be sober, be vigilant’ (1 Peter 5:8). It was borne by a number of early saints. The most important, in honour of whom the name was often bestowed from medieval times onwards, were Gregory of Nazianzen (c.329–90), Gregory of Nyssa (d. c.395), Gregory of Tours (538–94), and Pope Gregory the Great (c.540–604). A famous bearer of the name in modern times is the film star Gregory Peck (1916–2003). The name has traditionally been popular in Scotland, where it is often found in the form Gregor.

Irish: reduced Anglicized form of Gaelic Ó hAodha ‘descendant of Aodh’, a personal name meaning ‘fire’ (compare McCoy). In some cases, especially in County Wexford, the surname is of English origin (see below), having been taken to Ireland by the Normans.
