Adelaide Brooke's father
From Tardis Wiki, the free Doctor Who reference
Adelaide Brooke's father hid Adelaide in the attic during the Dalek invasion of Earth in 2009 and went out to search for his wife. Neither of them ever came back and their bodies were never found.
Adelaide reflected on this to the Tenth Doctor at Bowie Base One in 2059. (TV: The Waters of Mars)
Behind the scenes
Adelaide's father was played by Charlie De'Ath.
