[ANSTHRLD] Viking/Finnish name researching

[Alden Drake]

I'm helping Centurian Othar Morganson with some name research and could 
use a little help. Not being able to find Othar or Morgan to any 
cohesive construction, I'm looking at an alternative for him: Oddr Mogansson

Oddr – Viking Names Found in the Landnamabok:

Mogens - Finnish Names: 
http://sca.org/heraldry/laurel/names/FinnishNamesArticle.htm
This article lists the header Mogens, but references Mogans j Backby 
1564. Many of the referenced names here, show the patronymic name 
construction -son, for example, under the heading Mosen, lists Mosen 
Erichsson 1571. Mogensson, or Mogansson, should be suitable.

My question is: Is there a weirdness between Viking (Norse) names and 
Finnish names? There's obviously a temporal weirdness between these two 
names. I just want to avoid a second weirdness.

Thanks,
Alden
