Robert de Hauteville (born early 1060s?), [1] also called Robert Scalio [1] or Robert Guiscard II, [2] [3] was a younger son of Robert Guiscard, Duke of Apulia, and his second wife, Sikelgaita. The sources do not agree concerning whether he was older [1] or younger than his brother Guy. [4] Romuald of Salerno lists him before Guy. [5]
Robert accompanied his elder brother Roger Borsa in 1086, when the latter went to Palermo to confirm his possessions in the County of Sicily. He signed as a witness the document issued by Roger granting to the abbey of La Cava the monastery of the Holy Spirit in Bari. [3] He is last recorded in Sicily in 1096. [2]
John Tuzson argues that Robert later moved to Hungary in the following of his cousin, Queen Felicia, the wife of King Coloman of Hungary. [5] Felicia, unnamed, is described as "a lady of the highest nobility, daughter of King Robert Guiscard of Apulia" in the 14th-century Chronicon Pictum . [6] It is universally recognized that her father could not have been Robert Guiscard. It has generally been concluded that he was in fact Prince Robert I of Capua, but Tuzson argues that he was Count Roger I of Sicily, Robert Guiscard's brother. [5] He connects the younger Robert Guiscard and the queen's entourage to the Hungarian kindred of Oliver and Ratold, which the Chronicon claims originated in Caserta. [2] [7]
