Introduction
Cowesfield Esturmy is a manor established in Saxon times that stretches in a line from just south of the Parish Lantern to Cowesfield Green and northwards to the ridge of Dean Hill. It was one of three Cowesfield manors and named after the Sturmid family to distinguish it from the other two. The other two Cowesfield manors were another Saxon manor Cowesfield Spilman and a Norman one Cowesfield Louveras.
As well as a map below, I've included a number of views along the A27 showing where Cowesfield Esturmy starts and ends on the road..

The two maps below show the extent of Cowesfield Esturmy manor and a more detailed view along the A27. Along the A27 the manor of Blaxwell lies to the west and Cowesfield Spilman to the east. The southeast corner of the manor butts on to Cowesfield Green and Cowesfield Wood, the remaining woodland and common grazing for the two manors of Cowesfield Esturmy and Spilman. At the A27 the boundary with Cowesfield Spilman runs along Miles Lane (Forty Acre Lane). Further north the boundary leaves Miles Lane at Dean Lodge and includes Mean Wood. On this northern section the manor of Alderstone lies to the west of Dean Lane and along the ridge of Dean Hill to the north.
