William's Mother
William I - Odo of Bayeux - de Manaeville - Ranulf Flambard - Robert Curthose - Henry I - Adelaide of Normandy (Adeliza)
The heritage of William the Conqueror and who was associated with the Conquest is something that is not well explained. Apart from the Battle itself and the attempts to complete a list (roll) of those that "came over" with him is a bit of an over-simplifaction.
We do know, and it is well repeated, that William was an illegitimate son of Robert I, Duke of Normandy. Herleva was his mother and William went on to marry
Herleva - William I's Mother
If William the Conqueror had a half sister (Beatrix, supposed wife of Alphonsus de Vere) she would not
be a child by Herleva. Robert I, Duke of Normandy,
Herleva[a] (c.1005 – c.1050) was an 11th-century Norman woman known for having been the mother of William
the Conqueror, born to an extramarital relationship with Robert I, Duke of Normandy, and also of William's
prominent half-brothers Odo of Bayeux and Robert, Count of Mortain,
born to Herleva's marriage to Herluin de Conteville.
