Is it true that Kate is a descendent of Mary Boleyn? And also some King maybe?
If it turns out to be true, then she is:

Mary/Anne/George - Thomas Boleyn, 1st Earl of Wiltshire - Lady Margaret Butler - Thomas Butler, 7th Earl of Ormond - James Butler, 4th Earl of Ormond - James Butler, 3rd Earl of Ormond - James Butler, 2nd Earl of Ormond - Eleanor de Bohun, Countess of Ormonde - Humphrey de Bohun, 4th Earl of Hereford - Humphrey de Bohun, 3rd Earl of Hereford - Matilda Lusignan - Alix, Countess of Eu - Henry II, Count of Eu - John, Count of Eu - Margaret de Blois - William, Count of Sully - Adela of Normandy - William the Conqueror
So IF Kate REALLY IS a descendant of Mary Boleyn, then she's a direct descendant of William the Conqueror as well.
