Ann Gardiner was *possibly* the daughter of William Gardiner, grocer of London, and Helen or Ellen Tudor; Helen was the bastard daughter of Jasper Tudor, Duke of Bedford. William Gardiner and Helen Tudor had been thought by some to also be parents of Stephen Gardiner, Bishop of Winchester; the evidence is that they were not (they did have a son, Thomas, who became a Benedictine monk and prior of Tynemouth Abbey; there was a case entered by "the children of William Gardiner" for recovering the inheritance portion of Thomas who entered Westminster Abbey).
