In 1769 the Duke of Cumberland was sued by Lord Grosvenor for adultery with Lady Grosvenor. The evidence given in the divorce case was widely publicised, including what happened at Whitchurch.
Employees from the Red Lyon in High Street, where the couple were alleged to have had ‘criminal conversation’, were called upon to give evidence.
These witnesses included the eighteen year old grand-daughter of the keeper of the Red Lyon Inn, Mary Spencer, as well as the chambermaid Jane Richardson and her husband Joseph, the ostler.
