Manassès de Rethel

1. MANASSES de Rethel (-before 1115). A charter dated 1094 records absolution granted to "comitem Hugonem", with the consent of "filius eius comitis Manasses"[343]. William of Tyre names "Manasses" as younger brother of Baudouin who inherited Rethel from their father because his older brother was overseas but died childless[344]. It appears more likely that Manassès was the oldest brother, named after his paternal grandfather. No evidence has been found in the primary sources so far consulted that he survived his father and succeeded as comte de Rethel, apart from the reference in William of Tyre who specifies that his brother Gervais, who had been elected archbishop of Reims, resigned in order to marry after the death of his brother[345]. “Hugo comes et Milesindis collateralis” donated mills “super Axonam fluvium ante Rettestum” to Laon Saint-Vincent, with the consent of “filio nostro Manasse”, by charter dated 1097[346]. A charter dated 1115 records absolution granted to "Manasses filius Hugonis comitis" and "eo…mortuo" to "Gervasius frater eiusdem"[347].
