 By the time Coke returned to Britain , plans were already under way for him to enter Parliament . When an election was called in 1774 , Wenman stood for the seat of Norfolk , with his son asked to stand in his place for Derby . Coke was not particularly enthusiastic about this , and withdrew when his opponent discovered he was under 21 , the requisite age to stand for Parliament . With his father elected , Coke travelled with him to London , meeting members of the British high society . His sister Elizabeth and her husband James Dutton were also visiting , with Dutton 's sister Jane , and Coke fell in love with her . Wenman was not impressed when Coke asked him to let them be married , as he had picked out the daughter of a baronet for his son , but with the intercession of Wenman 's friend Harbord Harbord , he finally consented to their marriage , which occurred on 5 October 1775 .
