Emma of Hauteville [SEP] mother
Emma of Hauteville
Emma of Hauteville (fl. c. 1080–c. 1120) was a daughter of Robert Guiscard and Alberada of Buonalbergo. According to Ralph of Caen, she married Odo the Good Marquis and had two sons: Tancred and William, both of whom participated in the First Crusade. Tancred became Prince of Galilee and William died in the Holy Land. Her daughter Altrude married Richard of the Principate and was the mother of Roger of Salerno. 
Emma was dead by 1126, when Odo's second wife and widow
the crusaders of 1096, he mentions "Tancred, son of the marquis Odo the Good". Orderic's known erudition, and his contemporaneity with Tancred, make his testimony the best available on the latter's paternity. Only on the parentage of Odo's wife, Emma, does Orderic seem mistaken. Since Tancred and his brother William were both young at the time of the First Crusade, it is unlikely that their mother could have been a daughter of Tancred's namesake, Tancred of Hauteville.
