There's a theory that everyone's related to Charlemagne, though (well, everyone of European ancestry, anyway) - once you go back that many generations, everyone's related to everyone. It's called the ancestor paradox.

Being provably related (i.e able to actually trace the family line that far) is another matter though!

My family are from a small mining community new Newcastle. My family name (not the one I use now) is the name of a town a few miles away from where I grew up. It's frankly embarrassing how short a distance my paternal line has managed to move.
