Toponymy
Weston comes from the Anglo-Saxon for the west tun or settlement. Super Mare is Latin for "upon sea" and was added to distinguish it from the many other settlements named Weston.
Prior to 1348 it was known as Weston-Juxta-Mare ("beside the sea"). The name was changed by Ralph of Shrewsbury who was the Bishop of Bath and Wells. Between the 14th and 17th centuries the "super Mare" part of the name disappeared and it was just known as Weston, although in 1610 it was recorded as Weston on the More; môr being the Welsh word for sea.
