GUILLAUME (Rouen [900/05]-murdered Pequigny 17 Dec 942, bur ---, transferred [1064] to Rouen Cathedral[52]). Guillaume de Jumièges records that Rollo captured “Baiocasensem urbem” [Bayeux] along with "nobilissimam puellam...Popam filiam...Berengarii illustris viri" whom he married “more Danico” and by whom he had “Willelmum...filiamque...Gerloc”[53]. However, the Planctus for William Longsword[54], composed shortly after the murder of Guillaume, states that he had a Christian mother of overseas origin. Orderic Vitalis names "Willelmum cognomento Longam-Spatam" as the son of “Rollo dux” by his wife “Berengarium comitem...Popam...filiam eius”[55]. Dudo of Saint-Quentin states that he was born in Rouen and, in a later passage,describes him as a "young man" one year before his father's death[56]. His birth date is estimated based on the estimated birth date of his own son. His father chose him as heir one year before his death[57]. Flodoard records that "filius Rollonis" did homage to ex-king Charles III "le Simple" at "castellum…Auga" in 927[58]. He succeeded his father in [928/33] as GUILLAUME I"Longuespee" Comte [de Normandie]. Flodoard names "Willelmus princeps Nortmannorum" in 933[59]. Dudo of Saint-Quentin records that he quelled a rebellion led by the Viking chief Riulf after the latter besieged Rouen[60]. In return for swearing allegiance to Raoul King of France, Guillaume appears to have been granted rights to further territory along the coast in 933, maybe the Cotentin and Avranchin. If this is correct, it would have created rivalry with the dukes of Brittany. Dudo of Saint-Quentin describes Comte Guillaume's invasion of Brittany shortly after his accession to quell a rebellion against him, and his defeat of the rebels at Bayeux[61]. Responding to raids by Comte Guillaume, Arnoul I Count of Flanders invaded Ponthieu and in 939 captured Montreuil from Herluin Comte de Ponthieu, although it was recaptured by Comte Guillaume's forces. Guillaume of Jumièges records that “Arnulfus Flandrensis comes” captured "castrum...Monasteriolum" from “comiti...Herluino”, who sought help from “Normanniæ dominum” who recaptured the castle for Herluin[62]. In 939, Guillaume joined the alliance against Louis IV King of France which was led by Otto I "der Große" King of Germany who raided Frankish territory. Comte Guillaume, however, met King Louis at Amiens, receiving a confirmation of the grant of his lands in Normandy. Guillaume of Jumièges records that “Arnulfus Flandrensis” tricked "duci Willelmo" into a meeting to settle the dispute concerning Montreuil “apud Pinchiniacum”, where Guillaume was killed by “Henricus necnon Balzo, Robertus quoque atque Ridulphus quatuor diaboli filii” on “XVI Kal Jan” 943[63]. Orderic Vitalis records that "Willelmus dux" was killed in 942 “fraude Arnulphi Flandrensis satrapæ”[64]. The Annalibus Rotomagensibus record that "Willermus dux Normannorum filius Rollonis" was killed "943 XVI Kal Jan"[65]. The Brevis Relatio de Origine Willelmi Conquestoris records that "Rollo et Willelmus filius eius" were buried "apud Rothomagum in ecclesia beatæ Mariæ"[66]. Orderic Vitalis implies that the transfer of his body to Rouen Cathedral took place after the "the ninth year" in office of Archbishop Maurilius, who had succeeded Mauger de Normandie[67], which would date the event to [1064]. [m] firstly SPROTA, daughter of ---. Guillaume of Jumièges records that, after the rebel “Riulfus” was defeated at the battle of "Pratum-belli", a messenger arrived “a...Fiscannensis castri” and reported to Guillaume the birth of his son to “nobilissima puella Danico more sibi iuncta...Sprota”[68]. This passage suggests that Sprota was Count Guillaume's concubine rather than wife, particularly as no reference has been found to a dissolution of any marriage before she married Esperleng or before Guillaume married his second wife. She married Esperleng de Pîtres. Guillaume of Jumièges records that “Richardus I filius Willelmi Longæspatæ...mater eius Sprota” and “Asperlengi” had “filium Rodulphum...et filias plures”[69]. m secondly ([935]) as her first husband, LUITGARDIS de Vermandois, daughter of HERIBERT [II] Comte de Vermandois & his wife Adela [Capet] (before 925-14 Nov after 985, bur Chartres, Abbaye de Saint-Père). Rodulfus Glauber refers to the wife of Comte Guillaume as "sororem [Heribertum Trecorum comitem]", specifying that she was childless by her first husband, when recording her second marriage to "Tetbaldus"[70]. Guillaume of Jumièges records the marriage of “Normannorum Dux” and "Herbertus...filiamsuam", encouraged by “Hugone Magno”, after the marriage of Guillaume´s sister Gerloc [which would date the marriageto [935] if thatreport is accurate][71]. She married secondly Thibaut[I] Comte de Blois. "Hugonis ducis, Odonis comitis, Hugonis sanctæ Bituricensis archipræsulis, Letgardiscomitissæ, Bertæ comitissæ,Gauzfridi vicecomitis…" subscribed thecharter dated 985 under which "Robertus" donated property to "Sancti PetriCarnotensis", on the advice of "Odonem,simul cum sua matreLedgarde, pariterque dominam meam Bertam, ipsius æqueconiugem"[72]. The necrology of Chartres cathedral records the death "XVIII Kal Dec" of "Letgardis comitissa"[73]. Guillaume & his first [wife] had one child
