Mos of the 18th and 19th century trustees were titled men - dukes, earls, viscounts, baronets and there was even one son of Queen Victoria, Prince Leopold, Duke of Albany. Two Prime Ministers, Robert Peel and William Gladstone also served. Peel put in 22 years and Gladstone 33.
When Wolverton was expanded westwards in the early 1900s, some of the trustees gave their names to Wolverton Streets - Jersey Road, named after the 7th Earl of Jersey, Anson Road after Sir William Reynell Anson, Peel Road, after Viscount Peel, and Woburn Avenue after the 11th Duke of Bedford.
The practice of appointing trustee from the titled and their relatives seems to have continued. The only exception can find is the appointment of the distinguished astronomer Fred Hoyle who came from relatively humble origins. He served as a trustee from 1960 to 1973.
