Roger the Poitevin

[2] Roger acquired a great lordship in England, with lands in Salfordshire, Essex, Suffolk, Nottinghamshire, Derbyshire, Lincolnshire, Hampshire, and North Yorkshire.

[3] The principal part of the lordship was in what was then called inter Mersam et Ripam, that is, "between the Mersey and the Ribble"[4] and is now divided between Lancashire, Merseyside, and Greater Manchester.

Due to long established lines of communication across Morecambe Bay, Roger also assumed authority over the regions of Furness and Cartmel; these remained a part of Lancashire until as recently as 1974.

[7] Roger continued to be loyal to Rufus but in 1102 joined his brothers' failed rebellion against Henry I of England in favor of Robert Curthose.

In 1109, Roger was permitted to briefly return to England to the court of Henry I,[1] although he did not recover his earlier English holdings.
