Red Hair in Europe - Visualized

At Planet Ivy, James McInerney puts together a a nice map showing the occurrence of red hair in Europe.  Pretty much as expected, except, where did that Russian enclave come from?
Incidentally, if you've wondered about red hair's genetic origins,

The phenotypic manifestation of Red Hair occurs when an individual has two recessive alleles for the Melanocortin 1 Receptor.  This is a kind of GPCR protein (a type of protein that is usually found embedded in the membrane of a cell and that often mediates the transfer of information from outside to inside the cell or vice versa).  The gene for this protein is found on chromosome 16.  In any case, if you have the recessive alleles, then you produce phaeomelanin (a yellow-ish reddish skin and hair pigment) and not Eumelanin (the brown-black pigment).  If you have one recessive allele and one dominant allele, then you won’t have red hair and if you have two dominant alleles you won’t have red hair.

Better now, no?
Anyhow, it looks like the Russian enclaves are the Komi republic, and the Komi Permyak Orkyug
