Adelaide Brooke's father
From Tardis Wiki, the free Doctor Who reference
Mr Brooke was the father of Adelaide Brooke. During the War in the Medusa Cascade, after he sheltered her in their house, he told Adelaide to stay inside. He went out looking for her mother. After he left, a Dalek appeared outside the window. Once it saw Adelaide though, it flew away. Adelaide later said her father never came back and she never saw her mother again.
