Anslech or Anslec de Bricquebec (active in the 930s and 940s) played a major political role in the first days of the duchy of Normandy, though the sources on him are rather opaque.
Around 1000, Dudo of Saint-Quentin evoked Anslech as one of the three secretarii to the jarl of the Normans, William I (v.927-942).
[1] A later source, le Roman de Rou, explains that Anslech supported William when Rioulf began an important rebellion against him.
The sagas from Norway and the islands make Anslech a Norman noble, Danish or Norwegian in origin but always from the old Viking nobility.
A tradition - held since the 17th century, though with no evidence - considers him as the ancestor of the families of Montfort and Bertran via his son Tursten of Bastembourg.
