Adelaide Brooke's father

From Tardis Wiki, the free Doctor Who reference

Adelaide Brooke's father hid Adelaide in the attic of the family home during the Dalek invasion of Earth in 2009, while he 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)
