In "Dudo of St. Quentin, History of the Normans", book II, she is made the daughter of a count Bérenger. The Planctus of William Longsword does not provide her name, but states that she was a Christian, and mother by a pagan father (i.e., Rollo, whose name is also not given) of William, who was born overseas. The accounts given by Dudo and the Planctus are not necessarily contradictory (since Dudo places Rollo overseas in England not long after mentioning the marriage), but there is also nothing in the Planctus that could be seen as confirming Dudo's account. Attempting to identify count Bérenger further is probelmatic. According to Orderic Vitalis, Rollo "stormed and captured Bayeux, slew its count Berengar and took to wife his daughter Poppa". In another passage, the same source records that Rollo besieged Paris, captured Bayeux, killed "Berengarium comitem" and married his daughter Popa
