I just decided to look up Minna's name. Minna is an Old Germanic name, which comes from Wilhemina. It means "determined protector." As for her last name, Sundberg, I think berg, is a Nordic variation of the German "burg," which means mountain, mount, or cliff. In German, burg is the name for city, and a few German words, such as bürgermeister(mayor). As for "Sund," in Swedish, it means sound/healthy, or it can mean a sound or strait(referring to bodies of water). In Faroese, it also means sound or channel(water). So her last name could mean" (of the) on the sound/strait/ mountain on the sound/strait. So all in all, it's "determined protector of the mountain/city on the sound/strait( It's cool how the first name ties in with the last, although it's probably a coincidence). BUT, I could be wrong.
