Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful."

A modern form of the Old Norse Ragnvaldr and a relation of Reginald, Renaud, Ronald, and Reynold, Ragnvald is a rugged and strong name used predominantly in Norway and Sweden. Notable bearers include Scandinavian nobleman, Ragnvald Ulfsson the Old, footballer Ragnvald Soma, and illustrator and editor Ragnvald Blix.
