Alistair McGowan (S04E06)

Alistair McGowan has always assumed his family has strong Scottish roots, but he often wondered where he gets his dark eyes and skin tone from. His father was born in Calcutta but it was not only until after his death that Alistair realised there may be mixed Indian and British heritage in his family's past. Starting in Calcutta, Alistair traces his paternal line in India back to the mid-1700s. (BBC)
