They are Igbo...no surprise. Albinsim and various derivatives of it are SO common among Igbos of Nigeria. I believe they have one of the highest if not highest prevalence of Albinsim in Nigeria. Of course, there is also the Lost Tribe of Israel theory of Igbo orgin. Maybe this and albinism are just 1,000 year old genes resurfacing.
