Brian Anderson

(male) Of Irish origin: perhaps from an Old Celtic word meaning ‘high’ or ‘noble’. The name has been perennially popular in Ireland, in particular on account of the fame of Brian Boru (Gaelic Brian Bóroimhe) (c. 940–1014), a warrior who was credited with driving the Vikings from Ireland and who eventually became high king of Ireland. In the Middle Ages it was relatively common in East Anglia, where it was introduced by Breton settlers, and in northern England, where it was introduced by Scandinavians from Ireland. It was quite popular in Yorkshire in the early 16th century, largely because it had long been a family name among the Stapletons, who had Irish connections. They first used it after Sir Gilbert Stapleton married Agnes, the daughter of the great northern baron Sir Brian fitzAlan. In Gaelic Scotland it was at first borne exclusively by members of certain professional families of Irish origin.

Scottish and northern English: very common patronymic from the personal name Ander(s), a northern Middle English form of Andrew. See also Andreas. The frequency of the surname in Scotland is attributable, at least in part, to the fact that St. Andrew is the patron saint of Scotland, so the personal name has long enjoyed great popularity there. Legend has it that the saint's relics were taken to Scotland in the 4th century by a certain St. Regulus. The surname was brought independently to North America by many different bearers and was particularly common among 18th-century Scotch-Irish settlers in PA and VA. In the United States, it has absorbed many cognate or likesounding names in other European languages, notably Swedish Andersson, Norwegian and Danish Andersen, but also Ukrainian Andreychyn, Hungarian Andrásfi, etc.
