They lived on extensive estate and usually entertained many guests such as Charlotte Bronte, Alfred Lord Tenneyson and more. Mary was a London social leader and was an associate of Queen Victoria. William had made several trips to the U.S. And seemed to enjoy the west, he had provided generous financial assistance to photographer William Jackson, artist Thomas Moren and explorer Dr. Fernandad Hayden.
