Here's the game setup. The duke of Lower Lorraine is Godfried (IV?) d'Ardennes, born 1045. His father, also Godfried (III?) d'Ardennes, born 1005, is a courtier in the court of his second wife, Beatrice de Bar, the duchess of Toscana. Ide d'Ardennes, the sister of Godfried the younger, born 1035, is the wife of Eustache de Boulogne, count of Boulogne. Eustache and Ide have three children, Eustache (b. 1055), Geoffroy (b. 1060) and Baudoin (b. 1062). Living in the court of the count of Brabant, with no parentage given, is Godefroi de Boullion (sic), b. 1060. This Godefroi is either a duplicate of Geoffroy de Boulogne or another son of Eustache the elder, and should either be eliminated (if a duplicate) or moved to Boulogne, have his dynasty changed to de Boulogne and attached to Eustache and Ide as their son.
