You're thinking of Kennewick Man and the Ainu. I think the Ainu were associated with and after the Jomon who I believe came before this 'red-headed' group in this article. The oldest Jomon skeleton ever found, in Japan, is 11,000 years old. Some do associate the Ainu with the 'red-headed' group of this article but, they are in the minority. The Jomon are associated with pottery defined as 'cord pottery. (Incidently, 'cord' pottery has been found in the ruins of the Olmec (1400-300BC) of Mexico...go figure.)
