Nothing in MedLands. FabPedigree, which is not a reliable source, thinks she *might* have been a Roucy, but there is no evidence for this. Geneanet provides general evidence for her generation of the Roucy family but nothing for her specifically. It seems to be all "say-so" family trees.
(MedLands does not cover the Gondrecourts.)
Removing as daughter of Hugues "Cholet" de Roucy, Comte de Roucy, Seigneur de Nizy-le-Comte et de Sevigny pending Sources and Alex's input.
