Sir Thomas Kyme of Friskney, a Lincolnshire squire –according to Mary Anne Everett Green, the English royal family had never known such an unequal union. The exact date of the marriage is unknown: various sources indicate 1502, the period between the spring of 1502 and the beginning of 1504 or a few months after the death of Cecily's sister, Queen Elizabeth of York in 1503, but before the meeting of Parliament in January 1504. At a meeting of Parliament in January 1504, Cecily, along with William Willoughby, 11th Baron Willoughby de Eresby, and three other men who claimed the Welles inheritance, petitioned the king. Cecily knew well that Henry VII would be happy with any of her actions that would put the princess under suspicion, and therefore she only said that she wanted to choose a spouse, guided by the principle of "convenience, not profit". However, she feared that her marriage might be used as an excuse to dispossess her of the property that Cecily had used as Viscountess Welles, and that the king would feign displeasure with her affairs as an excuse to seize her lands. To avoid this, Cecily decided to give the king a bribe, which was a small part of her income, and a promise to return the rest of the property within ten years after her death; thus the bulk of her husband's inheritance was to remain in Cecily's possession. In her petition, referring to the restitution previously made on the Welles estates for her late husband, in fact, she asked to cancel this restitution, leaving her husband's possessions to her if she outlived the king, and for ten years to the heirs of Welles, if she died earlier. The reasons why the other Welles heirs joined the petition are not clear, but it is likely that they received some benefits from the princess herself who would have being lost if Cecily was dispossessed from her late husband's inheritance. The petition ended with a plea from all the signatories (Cecily, her third husband Thomas Kyme and the heirs of her second husband) for the mercy of the King. The reaction of the king to the petition and subsequent events are described inconsistently by historians. Mary Ann Everett Green writes that Henry VII endorsed the petition, approving it with the words "Let it be as it pleases". However, Rosemary Horrocks, James Panton and Garland Okerlund point
