Ginger is the term used to describe we the fair skinned, freckled and redheaded few of society.
Less than four percent of the worlds population consist of naturally redheaded gingers. It is more than fare to say gingers are a rare breed.
Gingers, better referred to as red heads, originated in the UK with most of the ginger population coming from Scotland. I myself am Scottish.
The first gingers recorded on earth were from Africa who later spread throughout the north regions of Europe.
The red head (ginger) trait is recessive and can therefore occur randomly in a family generally of other dark haired members. So the odd redhead in a family of non redheads is in no way a sign of foul play.
