In the east, Weeton occupies most of the southern half of the parish, with Mythop in the south western corner, the northern half containing Preese on the west and Swarbrick on the east. Watson argues that these sub-manors — each with its own hall — may be based on the ancient pre-Conquest quarterland divisions characteristic of the Irish Sea cultural basin of Celtic North Wales and the Isle of Man. Each of the four manors occupies an area of slightly higher ground, each divided from the others by depressions: Weeton is above sea level, Swarbrick and Preese and Mythop .
