I like the reference to the Jet Black Hair. That is what got me started on Genealogy quite a few years back. One particular line in my family has carried the same gene for centuries and it has always resulted in Black hair and very dark Brown eyes. This has variously been referred to as Spanish, European, African.
Hmm well I thought that was strange, Scottish was the supposed ancestors home. I have now gone back to the mid 1200's with the family and they lived in the border counties of N/E England. Although throughout the centuries many have moved about England and then throughout the world.
A DNA test revealed Celtic origin and through that early Celtic migrations from Moorish origins. So they were accidentally right, UK, Spain, Europe, Nth Africa.
Hmm so that's where my Black hair and Brown eyes comes from, probably yours too.

Not much Norman Blood in me, yet my brothers were all born with Blondie hair and fair eyes and don't have the same gene.........No it wasn't the milkman.

Just a freak of nature.
