They are also closely related to the Mari,a tribe of the original people from what is now called the "Mari Republic" in Russia.
There are other relatively small ethnic groups scattered around Russia, including the Urals, who speak Finno-Ugrian languages (or used to). There is a high proportion of blondes among the Finns I've seen, although many look quite different from Scandinavians. Most Hungarians I've seen look much darker. Some think the Magyar invasion of central Europe was accompanied by some Turkic ethnic elements.
