Another link exists into the Royal Windsor family through Sarah Ferguson via Wingfield, Meade, O'Brien, Fitzgerald, and then to Richard Óg de Burgh, a grandson of the said Egidia de Lacy, and a greatx5-grandson of Walter de Lacey the Norman soldier. This link makes Sarah Ferguson and her ex-spouse, Queen Elizabeth II's second son Prince Andrew, Duke of York, distant cousins.
