In one such case, it was rented by Lord Sinderby for a grousing party in Autumn of 1924, to which the Crawley family were also invited. Lord Sinderby makes the precarious decision to take his own butler, Stowell to the castle to see over both the upstairs world and below. Also in attendance were Henry Talbot, Charlie Rogers, and the agent, Bertie Pelham.
Bertie was also a distant cousin of Lord Hexham, with whom he was very good friends. When Peter passed away in 1925, Bertie stood as heir and became the 7th Marquess of Hexham. He and his widowed mother Mirada Pelham moved into the castle. She specifically lived in a suite of rooms that had been made into a flat "for an aunt".
Bertie, soon after his elevation to Marquess, married Lady Edith·克劳利, who thus became the Marchioness of Hexham. Edith's daughter Marigold was to move to Brancaster by the time she and Bertie returned from their honeymoon.
