4. [ JUDITH . The Genealogiciæ Scriptoris Fusniacensis names "Lebaldus de Malla et…Iveta comitissa de Retest" as brother and sister of "Ebalus de Roceio" and, in a later passage, "Iuetta soror…Letaldi de Marla" as mother of "Hugonem comitem de Retest"[413]. The Chronicle of Alberic de Trois-Fontaines names "comitissa de Reitest, uxor comitis Manesserii Iutta” as sister of "fratres Ebalus comes de Roceio et Letardus domnus de Marla"[414]. Hugues de Rethel names his parents Manassès and Judith in a charter dated 1081 for the church of Braux[415]. However, Judith Ctss de Rethel must have been born in [1020/30] for chronological consistency with the estimated birth dates of her descendants, which excludes her being the daughter of Giselbert Comte de Roucy. It is possible, as suggested above, that she was the uterine half-sister of Ebles Comte de Roucy, born from their mother's second marriage.
