Haha that sounds like a Meänkieli name (a language spoken in the Swedish side of Torniolaakso (Torne Valley)) where you borrow swedish words and Finnish-ify them.
Björninen sounds like me trying to come up with a Swedish surname in the 7th grade
My contributions, apologies if done already:
Mikko Rantanen = Mike Shore/Beach (I have no idea how to translate -nen)
Sami Lepistö = Sam Alderforest? Alderaan?
Ville Uusitalo = William Newhouse
Kristian Kuusela = Christian The-Place-With-Spruce
Bonus round (inspired by a signpost I just saw)
Göran Stubb = George Treestub
