In circa 1226 Alexander de Stavenby bishop of Lichfield founded the prebend of Tarvin which, at £26 13s 4d, was the highest endowment of Lichfield Cathedral. The prebend occurs at a similar date to the changes to the borders of Cheshire due to yielding some hundreds to Wales; furthermore Bishop Alexander de Stavenby was a diplomat acting for King Henry III both with France and spent time in Wales trying to renew truces. As the disputed Hundred of Dudestan (Duddeston) included manors only a few miles from Tarvin, such as Christleton, Waverton and Stapleford, the choice of Tarvin for the prebend (apart from it already being an episcopal manor) may have been carefully chosen to be on a boundary, but not as suggested above a boundary with the Forest of Delamere, but on the boundary between England and the disputed parts of the England/Wales border. These were the days of Llywelyn who was reported to have a strong alliance with the 6th Earl of Chester.
