About Rainulf "Drengot" Conte di Aversa, Duke of Gaeta
One of five brothers, parents unknown, who migrated from Normandy to Southern Italy and became very prominent in establishing Norman-Italian culture.
Orderic Vitalis (XXVI, 47) records that Osmand Drengot killed Guillaume Repostel while hunting in the forest at the court of Duke Robert of Normandy after Repostel boasted loudly of having seduced Drengot's daughter. Other accounts (Aimé du Montcassin et Pierre le Diacre) say it was Osmond's brother Gilbert. In any case, all five brothers fled to Rome for an audience with the Pope, and there they met Melo de Bari, who apparently became their protector in Italy.
RAINULF "Drengot" (-Jun 1045). The Chronica Monasterii Casinensis records that "Giselbertus…qui et Buttericus…[cum] quatuor fratribus suis, Rainulfo, Asclittino, Osmundo, atque Rodulfo" arrived in Capua (after Gilbert was banished from Normandy) where they joined "Melus", dated to [1015/16] from the context. Originally recruited by Guaimar IV Prince of Salerno to fight the Byzantines, Amatus records that Rainulf was enfeoffed with Aversa by Sergius IV Duke of Naples and married the latter's sister as a reward for having helped restore him to power in 1029. The Chronica Mon. Casinensis records "dehinc Sergius recuperata Neapoli, Rainulfum strenuum virum affinitate sibi coniunxit, et Aversæ illum comitem faciens". After his third marriage, he became the vassal of the Prince of Capua. In  he turned to support Salerno. He was invested as Conte di Aversa by Emperor Konrad II in 1038, as vassal of the Prince of Salerno. Guaimar IV Prince of Salerno installed him as Duke of Gaeta in 1041. Amatus records that "the Normans…decided among themselves to place a count over them…and…chose William, son of Tancred" and after installing him as their count “went to the court of Prince Guaimar of Salerno” who they asked “to make Rainulf a count over them” who was "count of Aversa whom they had left behind when they went with Arduin in search of conquests". Amatus also records that Rainulf was at the same time given the city of Siponto and part of Monte Gargano as his fiefdom. Duke of Gaeta: Amatus records that "Count Rainulf" was made "Duke of Gaeta", dated to [1043/44] from the context. The necrology of San Benedetto di Capua records the death in Jun of Rainulf.
m firstly (1030) as her second husband, --- of Naples, widow of --- Duke of Gaeta, daughter of IOANNES IV Duke of Naples & his wife --- (-1034). Amatus records that Sergius IV Duke of Naples gave his sister, "recently widowed by the death of the Count of Gaeta", in marriage to Rainulf in return for helping him resume power in Naples from Pandulf IV Prince of Capua. The Count (Duke) of Gaeta in question has not yet been identified. The Chronica Mon. Casinensis records "dehinc Sergius recuperata Neapoli, Rainulfum strenuum virum affinitate sibi coniunxit, et Aversæ illum comitem faciens". Amatus records her death soon after the marriage.
m secondly (1034) --- di Amalfi, daughter of SERGIUS III Duke of Amalfi & his wife Maria di Capua. Amatus records the marriage of Rainulf to "the Patrician of Amalfi's daughter, who was Prince Pandulf's niece [Pandulf IV Prince of Capua], as the Patrician's wife was Pandulf's sister".
[m thirdly as her first husband, EMMA di Loritello, daughter of GODEFROI de Hauteville & his first wife ---. This marriage is recorded in Europäische Stammtafeln but is improbable chronologically. Rainolf died in 1045, before Emma's father was first recorded in Italy. In any case, Emma could have been no more than an infant at the time of such a suggested marriage.]
