Rocastle
From Tardis Wiki, the free Doctor Who reference
Rocastle was the headmaster at Farringham School for Boys in the early 20th century. Rocastle was a strict disciplinarian who ran the school primarily to educate the boys on key subjects, and particularly how to fight. He was known to have been a combatant in the Boer Wars and expressed a desire to return to war in the name of "King and Country". He was killed by Daughter of Mine, a member of the Family of Blood.
