The State Papers and the Journal of Prior More of Worcester are the main sources for a detailed, though incomplete, record of the itinerary of Princess Mary in the Marches of Wales, 1525–7. Revised dates are proposed for several documents calendared in Letters and Papers . . . of Henry VIII which the princess’s biographers have misinterpreted, including some relating to the appointment of her council and household. References to the itinerary of the princess’s council are also noted. After returning to court early in 1527, the princess did not return to the Marches, probably because her prominent role there was no longer compatible with the king’s intentions concerning the succession.
