He has/had a relationship with Adele de Coucy.
Child(ren):
Leo van de Pas gives not wife for Dreux, and names his ancestors "deCoucy" as well. Leo could well be correct, but the ancestry I amfollowing (presumably RFC), would have Dreux's ancestors being "deBoves", while the Coucy lands came into the family with this marriage toAdele de Coucy.
