My own ancestry is odd. very odd. My mother is from a Cockney family, and that's that, but my father's family is where is gets interesting:
His mother's parents: mother: Isle of Wight; father: Scots/Irish (both, not "don't know"). The Scots side boils down to the Stewart family, if that means anything.
His father: Jewish by ancestry, but the family was resident in England for... about a thousand years: they were Norman Conquerors. They spent many generations in the Ribble Valley area (mainly in Oswaldtwistle).
