As her dowry, she brought Robert Guiscard 200 knights under command of her nephew Girard of Buonalbergo.
[2]In 1058, after Pope Nicholas II strengthened existing canon law against consanguinity, Guiscard repudiated Alberada on that basis, in order to make a then-more advantageous marriage to Sichelgaita, the sister of Prince Gisulf II of Salerno.
[2][4] This new marriage would hopefully serve to ally the Lombard and Normans; with Alberada and Guiscard's children simply too young to feasibly be married off, Guiscard may have determined to use himself.
She was alive at the death of Bohemond in March 1111 and died very old, probably in July 1122 or thereabouts.
[4][6][7] She was buried near the Hauteville family mausoleum in the Abbey of Holy Trinity at Venosa.
