The Vikings spreading the gene around makes a lot of sense, as red hair evolved in far north climates to deal with small amounts of Vitamin D, and the Vikings spread their gene pool around northern Europe quite a bit, through simple settlement or raping and pillaging. I know I got part of the recessive gene from my scots-irish side, and the Vikings had quite a bit of red hair too... and they invaded a lot of the baltic, and Poland too.
That's right. But, it wasn't only the Vikings who had red hair in the far north; some tribes out of Siberia on the western side of the Urals also had red hair. Red hair was also associated with Russian Jews early on in the very beginning of Kiev and Rus, going back to Kharzaria.
Supposedly 30,000 Scottich families settled in Poland back in the 17th century, i havn't met any Scottish Poles, did they evaporate lol ?? of course not, they've gotten completly asimilated into Polish society, therefore if you meet a red headed Pole, he's probably got some Scottish in him.
Except that the incidence of red hair in Eastern Europe was apparent way before the 17th Century, and developed independently of the Viking invasion as well. If red hair evolved due to a lack of Vitamin D, then it only follows and is actually supported that Siberian tribes independent of the Vikings also had this evolutionary gene. *(But, who knows if it was completely independent, because Siberian tribes in the far east never developed the same gene. But, they all have some degree of the eye fold to protect the eye from the glare of the sun). Due to various migrations out of the far north and into Central Asia and Eastern Europe, it is not a big surprise that red gene also naturally occurs to a lesser degree in Eastern Europe.
As for the Celtics tribes, it is my understanding that their settlements also originated in Eastern Europe somewhere around where the Czech Republic is now, until they migrated west, terrorized Gaul and crumbling Roman Empire for awhile, and crossed over. I have also met a few Czechs who have red hair.
I'll look for my links somewhere. I have them buried somewhere because I was conducting research on my own heritage from Eastern Europe and saved them.
Jampat about Vikings.... weell Tacitus (Romasn writer) mentions lots in N Britain many centuries before vikings came into Britain.
Yeah, probably that too. Aren't there still places in England with Viking names?
Ok, here are some quick links and excerpts (I couldn't find my other links at the moment, but these will do):
