Castles's list "Norse/Scandinavian Names" of 5 great name ideas: Astrid - SIGFINN!

Norse/Scandinavian Names

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." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
 
Astrid has never really assimilated into our culture the way Ingrid did, but with the renewed interest in international names, Astrid might be worth consideration by parents with Norse roots. 
 
Astrid is the name of the teenage heroine of Janet Finch's 1999 novel White Oleander and has appeared as a character in How to Train Your Dragon and the TV shows Fringe and Once upon a Time.
