Robert Scalio

Robert de Hauteville (born early 1060s?), also called Robert Scalio 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 Romuald of Salerno lists him before Guy.

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. 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.
