Roger I de Montgomery, who was the first to use the surname of Montgomery, was called one of the most powerful Norman Barons at the end of the tenth century. He died in Paris about 1040 A.D. He married Josceline, daughter of Senfrie, sister of the wife of Richard I. His sons were Hugo who died before 1050, Robert and William who both also died before 1050, Gilbert who was poisoned by his sister-in-law, Mabile de Belleme in 1063 A.D. and our ancestor Roger de Montgomery II, Earl of Arundel and Shrewsbury.

"Origin and History of the Montgomerys" by B.G. Montgomery of Sweden.



Gormeric's eldest son, William, had a son Hugo. His son Roger de Montgomery is the first member of the family of whom one knows with certainty that he used the surname. The French historian, the Vicomte Du Motey, calls Roger 'one of the most powerful Norman Barons at the end of the tenth century.'

William the Bastard, the name of the Norman Duke before he conquered England and gained the prouder surname of the Conqueror, was the son of Robert II and Arlette or Herleve, the daughter of one Fulbert, tanner of Falaise. Judging by his great care of churches and monasteries, Roger must have been a very religious man. No wonder, therefore, that after Robert's death he refused to recognize William, born out of wedlock, as the legitimate heir to the throne. He and his sons Hugo and Robert organized the opposition against the young Duke, whose guardian was Allan, Duke of Brittany. They struggled against heavy odds, since the Duke's supporters were far more numerous, but Montgomery defended himself with great courage and tenacity behind the walls of his castle. Allan died at Vimoutiers during the siege, but in the end Montgomery had to surrender. He was banished from the country and went to France, where he was well received by Henry I, who shared his views. Roger died in Paris about 1040. According to the Cartulary of Troarn, his wife Josceline was still alive in 1068.

During Roger's exile his sons remained in Normandy, continuing to fight for what they considered a just cause. This struggle eventually developed into sheer vendetta. Allan's successor as guardian of the young Duke was Osbern de Crepon, the son of Herfast, brother of Duchess Gunnor. He was a cousin of Richard II and also of Roger de Montgomery's wife Josceline. In spite of this kinship Osbern pitilessly persecuted Roger's sons, and one of them, William, determined to capture the Duke, who lived with Osbern in the strongly fortified castle of Vaudreuil. The guardian watched like a hawk over his precious life, but one night William and his confederates managed to penetrate within the castle to the Duke's chamber. He was not there, but Osbern, whom they found alone, was summarily strangled. Ordericus says that on this occasion the Duke's life was saved by his uncle Gautier, brother of Arlette, who had hidden him in his bed. Some days later one of Osbern's men, Bamous de Glos, surprised William in his quarters and killed him during his sleep. Now the vendetta was accomplished and the way open to reconciliation between the Duke's party and the Montgomerys.

The symbol of advance into Wales was the castle which Earl Roger built at Montgomery, a typical motte and bailey, of which the earthworks still survive. To distinguish it from the later stone castle built at Montgomery by Hubert de Burgh, it came to be known as Hen Domen Castle- the old mound. It was a key point in the natural communication into mid-Wales, and beyond that westwards to Ceredigion. The gains which Earl Roger and his commanders made were compact and, with the exception of Arwystli, did not drive deeply into Wales, but they extended over a long stretch of the frontier.

  1. 'Oft on the mouldering Keep by night
  2. Earl Roger takes his stand,
  3. With the sword that shone at Hastings' fight,
  4. Firm grasped in his red, right hand ! '

This is how an ancient poem begins about Roger de Montgomery who it was believed had fought alongside Duke William at Hastings. In fact Roger de Montgomery wasn't at the Battle of Hastings, but was left at home to look after Normandy for William while he was in England. He contributed greatly to the invasion force and was to be richly rewarded for his loyal services.

Earl Roger de Montgomery founded the Arundel Castle on Christmas Day 1067. It was after King William had held his Christmas Court at Gloucester and awarded Montgomery the Earldom, that he ordered him to build a castle on the Arun to protect the inland reaches. Roger de Montgomery was already an extremely powerful man in his native Normandy and had been a close friend of William's since William was a teenager as he was his cousin. He was present at the Council of Lillebonne in 1066, and agreed to contribute 60 ships to aid the invasion plans of England. He returned with William from Normandy in 1067 and he was summoned to attend Chrismas at Gloucester with the king where he was awarded his honours as one of William's most trusted men.

Earl Roger was succeeded at Arundel by his son, Robert, known as Robert de Belleme.

John Fitzalan of Clun, who had married Hugh de Albini's daughter Isobel, acquired the Castle and Honour of Arundel. The Fitzalan's were to hold the castle in an almost uninterrupted line until 1555 when Mary Fitzalan, last of the family, married Thomas, 4th Duke of Norfolk, thereby carrying Arundel into the Howard family where it remains to this day.
