 The 1st Duke was also Earl Temple of Stowe, a title which descended through heirs of his relatives should the male line become extinct.Consequently, on the 3rd Duke's death this title, with most of the Wotton estate, passed to his nephew William Temple-Gore-Langton who became the 4th Earl Temple.By this time construction of the MR extension from London to Aylesbury was under way, and on 1 July 1891 the MR absorbed the Aylesbury and Buckingham Railway.
