From the Old Norse personal name Rögnvaldr (composed of regin ‘advice, decision’ (also, ‘the gods’) + valdr ‘ruler’). This name was regularly used in the Middle Ages in northern England and Scotland, where Scandinavian influence was strong. It is now widespread throughout the English-speaking world.
English, Scottish, and northern Irish: distinguishing name (Middle English yunge, yonge ‘young’), for the younger of two bearers of the same personal name, usually distinguishing a younger brother or a son. In Middle English this name is often found with the Anglo-Norman French definite article, for example Robert le Yunge.
