Roger was the son of Hugh de Montgomery (955-1056) and Sibell De Crepon (1000-1046), both of Normandie, France. Roger was born 975 in Saint-Germain-de-Montgommery, Calvados, Normandy, France. Roger"s wife Josseline de Pont-Audemer was born in 975 in Pont-Audemer, Eure, Haute-Normandie, France.
He died on 7 February 1055 in Île-de-France, France
She died in Pont-Audemer on 7 February 1050. She was the niece of Gunnora, Duchess of Normandy. Roger held the lands of Saint-Germain-de-Montgommery and Sainte-Foy-de-Montgommery, both of which show traces of early castles.
He acquired the office of vicomte of the Hiémois probably about the time Robert I became Duke in 1027.
In c. 1031–1032 he witnessed a charter to the abbey of Saint Wandrille by Robert I, Duke of Normandy as vicomte. Like Duke Robert, Roger began acquiring church properties, among these, c. 1025-1027, half the town of Bernay.
He took over a wood at "Crispus Fagidus" which belonged to Jumièges Abbey in the 1030s. He suppressed a market held by the same abbey and transferred it into his own domain.
He later returned the market to the abbey and paid restitution for their losses.
Roger seems to have lost favor with the young duke as well as his vicomte office as he signed an early charter of Duke William simply as Roger of Montgomery. Roger had been forced into exile by Osbern the Steward who was afterwards killed by William de Montgomery, Roger"s son. Roger died on February 7th 1055 in exile in Paris, Ile-de-France, France.
