This is a list of names in which the categories include Welsh Nobel laureates.
BertrandmFrench, English, Germanic Derived from the Old German elements beraht meaning "bright" and rant meaning "rim (of a shield)". From an early date it has been confused with Bertram and the two names have merged to some degree. Saint Bertrand was an 11th-century bishop of Comminges in France. Another famous bearer was the English philosopher Bertrand Russell (1872-1970).
BrianmEnglish, Irish, Old Irish Meaning uncertain, possibly related to the old Celtic root *brixs"hill, high" (Old Irish brií) or the related *brigā"might, power" (Old Irish briíg). It was borne by the Irish king Brian Boru, who thwarted Viking attempts to conquer Ireland in the 11th century. He was slain in the Battle of Clontarf, though his forces were decisively victorious. This name was common in Ireland after his time, and it was introduced to northern England by Norse-Gael settlers. It was also used in Brittany, and was brought to England by Bretons in the wake of the Norman Conquest. Though it eventually became rare in the English-speaking world, it was strongly revived in the 20th century, becoming a top-ten name for boys in most regions.
ClivemEnglish From an English surname derived from Old English clif meaning "cliff", originally belonging to a person who lived near a cliff.
