List of Famous people named Serlo

Serlo I of Hauteville was a son of Tancred of Hauteville by his first wife, Muriella, probably the youngest, though some sources call him the eldest. Born before 1010, he was the eldest son of Tancred's to remain in Normandy. After a dispute with a neighbour, whom he killed over an insult, Serlo was exiled for three years. Around 1041, his father died and he inherited the small fief of Hauteville in the Cotentin and the sirery of Pirou through his wife. He was regarded, as were his brothers, as an exceptional warrior.

Serlo II, son and namesake of Serlo of Hauteville and grandson of Tancred of Hauteville, went to seek his fortunes in the Mezzogiorno along with his numerous uncles and cousins, following Roger around 1056, for he is found in Calabria in 1060.
