Hi Curt, I've been over to the Hull Royal Genealogical Database trying to find descendents of Wm. the Conqueror and connections to Odard through the Count of Eu (which I have not found). But here it is reported that Wm had a sister. Associated with , Herleva (Arlette), Officer of the Household Child 1: , Adeliza of Normany, Countess of Aumale, b. 1029 Child 2: , William I the Conqueror, King of England, b. 1028 In generation 18, you reported that you had not found a sibling of Wm, so I thought that I'd pass this on to you. http://www.dcs.hull.ac.uk/cgi-bin/gedlkup/n=royal?royal01525 Take care, Carole
