Hope_Reborn's list "Norwegian princesses" of 3 great name ideas: Astrid - Ragnhild!

Norwegian princesses

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.

The name of our first First Lady still has something of a prim and proper image, academic and efficient. That quiet, traditional, and tasteful gestalt is exactly what makes Martha appealing to some parents today.
 The New Testament Martha, sister of Lazarus and Mary of Bethany, was a solicitous housekeeper who looked after the material welfare of Jesus when he was a guest in her home. For this reason Martha has since been identified with domestic labor and hospitality and is the patron saint of housewives, waiters, and cooks (a la Martha Stewart, who shares her name with her mother).
 Martha has been a royal name in Scandinavia, the subject of Beatles song "Martha My Dear," and is also associated with the New England island Martha's Vineyard. Livelier foreign forms that have been used in this country include Marta, Martine, and Martina.
 Modern dancer/choreographer Martha Graham would make a notable namesake for a dance aficionado.
