Are you are looking for a book that describes the descent of the Norman dukes from the Viking age? Are you looking for some material describing what it was like where Odard came from? Try this: The Dukes of Normandy and their Origin by The Rt. Hon. Earl of Onslow, PC, GBE, FSA, FRHistS published by Hutchinson & Co., London The photocopy I have of some chapters does not include the date of publication, but it was sometime in the early-mid 20th century. When the Norsemen arrived in what was later to be called Normandy, they were not only not Christians, they were what the 16th and 17th centuries would have called pirates. Fathering children with one wife was hardly in their minds. Onslow says "By Rollo himself, who no doubt had wives in every port from the Baltic to the Seine, the matter would have been regarded as of the most trivial importance." I doubt that we would use the word "wives" in this regard today. Later generations of the dukes shared the experience of "taking" women who were not their married spouse and having children by them. William was known as William the Bastard first, William the Conqueror only later. This practice evidently extended throughout the Norman hierarchy. This was not a monogamous society, even after it became Christianized. This may be one of the reasons that there will never be a clear ancestry for Odard. While later generations may have invented one to meet the requirements of their times, it is possible that Odard might not have been too sure of his parentage himself. Doug Hall
