Roose has been in existence since at least 945 AD. Roose is mentioned in the Domesday Book as one of the townships forming the Manor of Hougun which was held by Tostig Godwinson, Earl of Northumbria. Roosecote and Roose were originally two separate entities. Roosecote was founded by Michael le Fleming (of Aldingham) some time between 1107 and 1152. By 1157 both Roose and Roosecote were granges belonging to Furness Abbey. In 1537 with the dissolution of that abbey they returned to the Crown along with the rest of the abbey's lands.
