Esther Vanhomrigh or Van Homrigh, an Irish woman of Dutch descent, was a longtime lover and correspondent of Jonathan Swift. Swift's letters to her were published after her death. Her fictional name "Vanessa" was created by Swift by taking Van from her surname, Vanhomrigh, and adding Esse, the pet form of her first name, Esther.

Jonathan Swift was an Anglo-Irish satirist, author, essayist, political pamphleteer, poet, and Anglican cleric who became Dean of St Patrick's Cathedral, Dublin, hence his common sobriquet, "Dean Swift".
