I googled language in Iceland and this was at the top:
Icelandic is a Northern Germanic language with about 300,000 speakers in Iceland (Ísland), Canada (Kanada) and the USA (Bandaríki Norđur-Ameríku). Icelandic is the closest of the Northern Germanic languages to Old Norse and it is possible for Icelandic speakers to read the Old Norse sagas in the original without too much difficulty.

So, I would just use the Norwegian set. Not that it matters, since Iceland has a zero for baseball.
