Henry never was duke of Burgundy. He was married to Sybille of Barcelona. Henry's brother Hugh was duke of Burgundy, and married to Sybille of Nevers. French Wikipedia has son Fulk marry Alix, daughter of Hilduin IV de Montdidier (c998-c1063). Alix seems to have married a different Lord of Grandson, however.
