A marriage alliance with Scotland was made in 1473 promising Cecily to James, the infant son of James III, but Cecily was still unmarried at her father's death in 1483. Her uncle, Richard III, arranged Cecily's marriage to Ralph Scrope of Upsall, but Henry VII dissolved the marriage in 1486 and she married John Welles, Viscount Welles, the King's half-uncle. After Welles' death in 1499, Cecily went on to marry Thomas Kyme of Friskney. Cecily died in 1507.
