"Grayrigg. . . Having now advanced to the Eastern extremity of the parish of Kendal, we incline Northwards to the manor of Grayrigg; so called probably from being frequented by badgers, brocks, or grays; as on the east side of the river Lune, opposite thereto, is a place which yet bears the name of Brockholes. The hollow between is called Grayrigg-hause, from haustus perhaps, which signifies a draught; even as yet a throat or gulley is by the common people called a hause. There is a meeting-house in Grayrigg belonging to the Quakers."
