Well would you look at that, that's odd... I guess it's fine then, I guess ther is also a Hjorrun or something in Skyrim. And there were a lot of sen names in the early early TES games, the y don't seem to pop up too often.
Ok, language lesson:
Swedish, Danish, and Norwegian are pretty similar and if you know one understanding and learning the others isn't all that hard, however it's not always easy to communicate as some people have weirder dialects than others. In my experience Norwegians understand the most of what both parts are saying, maybe it's because we've been in unions with both countries. Anyways written Danish and Norwegian is pretty similar, at least the most common forms as we have two written forms of Norwegian and one was based around danish and is similar to a lot of the dialects in the east around Oslo, and the other written form is based on dialects all around norway and some people thinks it sounds Swedish (stupid norwegian teenagers, nynorsk was one of my better subjects in school). Spoken, Swedish is easier to understand than Danish, this is mainly die to pronounsiation where the danes don't always pronounce stuff as clearly as we would like, some people compare it to speaking Norwegian with a potato down your throat. Danish also have some words that are more similar to German if not the same.
Now Icelandic is kinda the odd one out here as it's closer to norse and I'm not sure if I could say older language, they've also done their share in preserving it, not importing words from English or French but making their own occationally, like a Garrage is a Garrage in most languages, but the translation from Icelandic would say Car-shed or Car-shack. Now Icelandics have danish in school as faras I know and understand most things, they can understand nynorsk if spoken slowly, just as an example. Icelandic is sometimes hard to understand when spoken, if you read it it's not all that hard, though some words might be foreign, you know and reckognize enough words to understand what is being said, the same goes for norse if you get the texts written in the latin alphabet, at least most of the time.
Icelandic also uses different letters such as the eth and the thorn, which is similar to the th sound that you have in English, this sound is not common if used at all anymore in Danish, Swedish and Norwegian. So they are all somewhat close, but Icelandic is kinda difficult and the one that stands the most out from the others.
I hope that made sense.
As far as the name I will have to think of that one, a favourite of mine is Gandalv (he was a viking king/chieftain, look it up), H?rek (Haarek) which is a classic person from the sagas and the name of Hagar the Horrible in the Norwegian translations. Names such as H?kon, Olav and Harald are of course classic if you are a king. Rolf or Rolv is also a classic figure, as you have Gange-Rolf (Rolf the Walker) who might be more known as Rollo the Viking. Eirik is a good one, Eirik Bloodaxe was quite the viking. Skallagrim is an uncommon but well know name, some ugly big and strong dude mentioned in connection with his son Egil. Halvdan is another good name, along with Geir (which means spear) Asgeir (Gods spear).
Of course there are also the good animal names. Bj?rn (or Bjorn Bjoern etc.) which means Bear, Ulv or Ulf which weans wolf, ?rn which means Eagle, Ravn (Hrafn can work too I guess) which means Raven. Elg, which means Moose. Objects Stein, which means Rock, Steinar which means Rock Warrior.
Hope that helps.
Maybe they just didn't give a [censored].
Back on topic.
As far as the build, I still think it looks fine, my shaman/whitch doctor people have usually been, restoration, illusion and conjuration with focus on Necromancy, but I guess that depends on how your fictional tribal culture works.
