On the night that Herleva fell pregnant with William she had a dream where in the dream a tree erupted from within her stomach and grew so big and so tall that it covered all of Normandy, but it did not stop growing there. The tree is said to then grow and cover the English Channel and continue until it covered all of the kingdom of England. Some say the story may have been invented later to give William’s claim even more legitimacy. One thing for sure that night was that the growth of an important figure in the history of North West Europe was beginning.In 1027/1028 she bore fruit of the relationship with Robert and William was born.
