Terve and the current name Tarvin, the village has also been referred to as Tervyn (e.g. in records of an assault on a monk in 1326) and Terfyn in the accounts of a trip from Chester to London in 1811, in which is it again suggested that Terfyn comes from the "British" word for "boundary", though in this case it is suggested this might refer to the boundary of Delamere Forest. 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. Ormerod's accounts show that this relationship between Tarvin and the Bishops of Lichfield and Coventry (the two bishoprics were merged in 1228) became long term, and continued until 10 April 1550 (well into the English Reformation), when "Richard, bishop of Coventry and Lichfield, granted this manor to Sir John Savage". Under Sir John Savage, Tarvin was elevated to a market town. Grammar School Tarvin Grammar School was founded by Randall Pickering junr., a freeman of the Haberdasher's Company living in St Martin Pomary, London, whose father was born in Tarvin. Having given £40 in his lifetime for the building of a schoolhouse, his will of 1641 gave a further £20 for the finishing of it, the first schoolmaster to be nominated and chosen by his two executors, who were also his kinsmen. The will also provided an endowment of £200 for purchase of lands, the rents from which were to support the school: lands were purchased in Tattenhall. The number of children was limited
