King Offa of Mercia is recorded as having given the Manor of Goosey to Abingdon Abbey in the 8th century AD in exchange for Andresey, an island adjacent to the abbey.
Later King Offa of Mercia built Offa's Dyke from the mouth of the River Wye near Chepstow to Chester and local remains can still be seen in the nearby Hudnalls Wood.

During Cuðred's reign, the Archbishopric of Lichfield was formally abolished at the Council of Clovesho on October 12, 803, and the Archbishopric of Canterbury thus regained the status of which Offa of Mercia had sought to deprive it.
The later Mercian kings Æthelbald, Offa and Ecgfrith were descended from Eowa; the period of their rule began in 716 following the death of Penda's grandson Ceolred and ended with Ecgfrith's death in December 796.
