The new Dr Who, Matt Smith, is to appear on the television series Who Do You Think You Are, which is a genealogy programme that traces back peoples family tree which usually results in some surprising results.
Former Dr Who David Tennant, was previously on the programme and was surprised to find that as well as his Scottish roots some of his ancestors were from Northern Ireland, from the Protestant community and they got involved in vote rigging to maintain control of the London Derry Council against a Catholic majority.
Jeremy Clarkson, who thought checking out his ancestors would be boring was astonished to find that his Maternal Grandmother was from Glasgow, and lived in a small one bed room flat.
Years ago there could be as many as ten family members in some of these small Glasgow flats.
Who do you think you are?
