About Anslec de Bastembourg, seigneur de Briquebec

Anslec (Lancelot) de Bastembourg, ancestor of the barons of Briquebec, son of Hrolf Turstin, was a powerful lord in early Normandy. Tradition attributes the foundation of the château at Briquebec, in the northern Cotentin Peninsula (la Manche) of Normandy, to the Norman, Anslech. The dukes of Normandy made Bricquebec one of their strongholds.

Anslec played a powerful political role after Duke William Longsword was assassinated in December 942. Then, he became part of a triumvirate which directed the future of the Norman duchy during the minority of Richard, partnering with Bernard de Pont-Audemer, Osmond de Conteville and Raoul Taisson.

Anslech de Bricquebec

From Wikipedia

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.

In the Anglo-Norman chronicles

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). He thus makes him a part of the entourage close to the son of Rollo.[1] A later source, le Roman de Rou, explains that Anslech supported Guillaume when Rioulf began an important rebellion against him.[2]

We see the same figure again in the writings of William of Jumièges. After the assassination of William I, Anslech, Raoul (called Taisson l'Ancien) and Bernard the Dane formed what William of Jumièges called "guardians of the whole duchy of Normandy",[3] awaiting the majority of the new duke Richard. In 943, they welcomed the king of the Franks, Louis IV to Rouen, who came as overlord to receive the homage of the inhabitants of Rouen.

Rise and fall

The sagas from Norway and the islands make Anslech a Norman noble, Danish or Norwegian in origin but always from the old Viking nobility. Son of Rollo Turstain Brico (or Hrolf Turstan), a supposed nephew of Rollo, in these he was the grandson of a certain Rollanger Rognvaldsson, a half-brother of Rollo, and the great-grandson of Rognvald Eysteinsson.[4] This genealogy is noted proven.

All the same, his descendents continue to be discussed. 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.[5] Finally, he is traditionally presented as the founder of the castle of Bricquebec in Cotentin (perhaps at the beginning of the 10th century), from which comes his nickname Anslech of Bricquebec, though this too is an assumption.

SOURCE: Anslech de Briquebec - alias Oslac de Briquebec, a powerful baron, associated with [] Bernard the Dane in the administration of Normandy - tutor to 'Duke' Richard of Normandy. He married Gillette de Beaumont -unknown pedigree. In the rebellion of Richard de St. Saveur, son of [] Helgi against [] 'Duke' William Longsword, in 933, Anslech is mentioned by Wace as one of the three Barons who alone remained faithful to the Duke, his second-cousin, by rendering him military service at the seige of Rouen. Their son was Turstain de Bastembourg, 'père de Guillaume, tige des Bertran' [Gustave Saige, Cartulaire de la seigneurie de Fontenay le Marmion, p. 29, 1895]. 'It is deserving of observation that the senior branch of the family held the extensive barony of Bricquebac in Normandy for eight successive generations. The last died as late as the 14th Century, leaving his large possessions, and the castle of Bricquebec, which one of his early ancestors had built, to his eldest daughter, who carried them by marriage to William Paisnel [Paganel], Baron of Hambie' [Memoirs Chiefly Illustrative of the History and Antiquities of Northumberland, Royal Archeological Institute of Great Britain and Ireland, vol. ii., pp. 48-50, 1859]. Ertemburge de Briquebec, married her second-cousin [] Torf the Rich - conveyed Crispin lands to him as maritagium.

UNKNOWN de Montfort-sur-Risle was our ancestor through two distinct descent lines--one through his son Toustain and the other through his daughter Gisela, each of whom was independently our ancestor.
