David Merrison's father
From Tardis Wiki, the free Doctor Who reference
Mr Merrison was the father of four children. After his two oldest sons and daughter had been taken by an alien, over three successive Christmases, he and his wife became distant, rarely showing affection for their remaining child, David.
When the next Christmas came, the Seventh Doctor and Ace successfully negotiated the return of the Merrison children, and they became a happy family again. (PROSE: But Once a Year)
