One of my friends actually has bright red hair and freckles. Apparently no one in her family has it. The only member that had it was her father's great grandmother.
Ok, so that's sooooo far back and she's long, long dead. Wouldn't a recessive gene like that normally disappear and not survive?

Genes only disappear if they're either detrimental or very unlucky.
In other words if the gene for red hair caused you to have fewer children than if you didn't have it.
It was very rare and by chance none of the people who had it had children or they lived only in one region, and everyone in that region died in an earthquake.1
