Aoife O'Sullivan Campbell is a character on The Vicar of Dibley. She was played by Orla Brady.
She is the woman who Tristan Campbell wanted to marry. She came to The Vicarage on christmas day and Tristan asked Geraldine to marry them. Geraldine accepted even though she was hurt by the mistaken request. Geraldine also initially seems to have trouble pronouncing Aoife's name correctly (pronounced EE-fa).
