'George III is alleged to have married secretly, 17th April, 1959, a Quakeress called Hannah Lightfoot, daughter of a Wapping shoemaker, who is said to have borne him three children. Documents relating to the alleged marriage, bearing the Prince's signature, were impounded and examined in 1866 by the Attorney General. Learned opinion at the time leaned to the view that these documents were genuine. They were then placed in the Royal Archives at Windsor; in 1910, permission was refused a would-be author who asked to see them. If George III did make such a marriage when he was Prince of Wales, before the passing of the Royal Marriages Act in 1772, then his subsequent marriage to Queen Charlotte was bigamous, and every monarch of British history since has been a usurper, the rightful heirs of George III being his children by Hannah Lightfoot, if they ever existed.' from Britain's Royal Families by Alison Wier, published by Jonathan Cape/Pimlico.
