River Eitha
River in Wales
The River Eitha (Welsh: Afon Eitha) is a small river in Wrexham County Borough, Wales. It is part of the River Dee catchment. Its name was probably derived from the Welsh word eithaf - "extremity", "farthest".
Sir Cyril Fox, in his surveys of Offa's Dyke and Wat's Dyke, identified a section of the Eitha as forming part of the frontier of Mercia in this area.[1]
