Catherine, Duchess of Cambridge & Gilly Wood are 15th cousins twice removed
My Notes: Controversy surrounds the heritage of Mary Boelyn's sons.  It will be interesting if DNA evidence becomes available to conclusively link the Descendants of Mary's sons with the legitimate Descendants of King Henry VIII. While I have placed this post in good faith I note that absolute proof (at present) is absent.
