Joanna (The Crusade)
From Tardis Wiki, the free Doctor Who reference
Lady Joanna was the sister of Richard the Lionheart and King John. While she was in Palestine with the former, Richard I tried to arrange to marriage between his sister and Saphadin in order to broker a peace between the English and Saladin's people, the Saracens. Joanna herself, however, very much opposed the plan and refused it. (DW: The Crusade)
