DREUX [Drogo] de Mantes (-[13 Aug] [1035]).

• "Walterius comes" donated property "prope nostrum castellum…Medanta" to "Carnotensi monasterio Sancti Petri", for the soul of "coniugis mee Adelidis filiorumque meorum", by charter to [1006], signed by "Walterii comitis, Rodulfi filii eius, Drogonis filii eius…"[1301].
• He succeeded his father as Comte de Mantes.
• Comte d'Amiens. "Droco comes Ambianensium" donated property to "Sancti Petri Gismoensis" by undated charter, signed by "Droconis comitis, Eotde comitissæ, Falconis fratris comitis, Rodulfi filiii comitis, Gualterii alterius filii…"[1302].
• He accompanied Robert II Duke of Normandy to Jerusalem and died on the journey[1303]. According to Orderic Vitalis, Henri I King of France took back the Vexin after the death of Comte Drogo[1304]. The necrology of Reims Saint-Rémi records the death "X Kal Aug" of "Drogo comes"[1305].

m ([1025 or before]) as her first husband, GODGIFU [Goda] of England, daughter of ÆTHELRED II "the Unready" King of England & his second wife Emma de Normandie (-before 1049).

• Her parentage is stated by Orderic Vitalis, who says that Godgifu went into exile in Normandy with her brother[1306] in 1013. According to Orderic Vitalis, her first marriage was arranged by Robert II Duke of Normandy[1307], indicating that she probably did not return to England. This information is suspect, assuming that the charter of "Robertus Rex", which names "Comes Drogo…cum duobus fratribus Fulcone…et Rodulpho necnon uxore cum filiis supra memorati Drogonis", is correctly dated to 1025 as Duke Robert did not succeed as duke until 1027[1308].
• Another possibility is that Drogo's children at that date were born from an earlier otherwise unrecorded marriage. There is no indication of the birth dates of his known children shown below, but the fact that none of them was given a typically Anglo-Saxon name also suggests that Godgifu may not have been the mother of all of them (although she is attested as mother of the son Raoul, see below).
• "Droco comes Ambianensium" donated property to "Sancti Petri Gismoensis" by undated charter, signed by "Droconis comitis, Eotde comitissæ, Falconis fratris comitis, Rodulfi filiii comitis, Gualterii alterius filii…"[1309].

Simeon of Durham names "earl Rodulph the son of king Eadward's sister Goda" in 1051[1314].

The necrology of Saint-Père-en-Vallée records the death "IV Non Aug" of "Gualterius comes"[1322], which may refer to Comte Gauthier [III].
