About Osmond "Drengot" di Aversa
One of five Norman brothers who fled Normandy and settled in Aversa in Southern Italy, establishing the first Norman presence there.
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.
OSMOND (-[after 1022]). 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. Orderic Vitalis records that "Osmund surnamed Drengot" fled "from the wrath of [Robert II Duke of Normandy] first to Brittany, then to England and finally to Apulia" where he was "the first Norman to settle" and was granted "oppidum" by "principe Beneventanorum", dated to [1015/16] from the context although this is inconsistent with the reference to Robert II Duke of Normandy. Guillaume de Jumièges records that Osmond Drengot killed "Guillaume surnommé Repostel" and escaped to Apulia. Amatus records that they joined forces at Capua with Melus, another exile from Apulia, and together returned to fight the Greeks. The Chronica Monasterii Casinensis records that "Stephano autem, Melo et Petro nepotibus præfati Melo" were granted "comitatum Cominensis" (by Emperor Heinrich II) together with "in auxilium Normannos, Giselbertum, Gosmannum, Stigandum, Torstainum balbum, Gualterium de Canosa et Ugonem Falluccam, cum aliis decem et octo", dated to  from the context. Chalandon identifies these Normans as "Gilbert, Osmond, Asclettin, Toustain le Bègue, Gautier de Canisy et Hugues Falluca". m (before [1010/15]) ---. The name of Osmond's wife is not known. Osmond & his wife had one child: a) daughter ([1010/15]-). According to Orderic Vitalis, Guillaume Repostel "boasted at [the Norman] court of seducing" her and was killed by her father "in the arms of Duke Robert whilst they were hunting in the woods", although other sources state that Osmond's brother Gilbert was the murderer. If the latter is correct, this may have been Gilbert's daughter. Her birth date range is estimated on the assumption that the story of Orderic Vitalis relating to her seduction is true and that she was of marriageable age at the time.
