The various Finno-Ugric languages of the Finnish branch live from the Urals to Finland in the North of Russia. I note some Ukrainian nationalists want to deny that Russians are 'true' Slaws on the basis that Moscow's missionaries Christianised a lot of Finno-Ugric people and  the populations merged... with present-day Udmurt etc. speaking populations as mere left-overs. No idea if there is any quantitative data on the mixing and on the modern 'Russian' gene pool, tough.
