Daughter of Raoul de Coucy

Who, exactly, she is, is uncertain, but she was NOT Yolande de Hainaut.

Raoul de Coucy and Agnes of Hainaut (sister of Yolande de Hainaut) had at least three daughters: Yolande de Coucy, who married Robert (II) comte de Dreux ; Melisende, who married Raoul [I] Comte de Roucy (*not* Coucy) and then Henri [III] Comte de Grandpre ; Ada, who married Dirk van Beveren.

Raoul's second wife, Alix de Dreux of the family Capet, contributed at least one more daughter, Agnes, who married Gilles de Beaumetz.

Any additional daughters, by either wife, are un- or under-documented.
