Civil War trench, is very rare. The Saxon cross may have been broken up before the assault of Chester in 1645 by the Parliamentary garrison. Tarvin appears as a substantial manor in the Domesday Book of 1086 (listed as Terve), the largest community in the Hundred of Rushton with 30 households. Tarvin Manor comprises some 2000 acres of cultivable land (22 ploughlands) as well as 'woodland'. The Domesday Book records the Lord of Tarvin Manor in 1066 as the bishop of Chester St John, and the same in 1086 but adds the name William Malbank, who was named as Lord or Tenant-in-Chief across over 100 manors in Cheshire after the conquest. According to Ormerod "Tarvin is one of the few Cheshire manors which experienced no change in its proprietor at the Conquest, being the property of the Bishop of the diocese, who retained his former possessions after that event." (The nearby Manor of Burton was also to stay the property of the Bishop of St John's.) Although the manors stayed with the bishops, the bishops changed to Norman appointees. Bishop Peter moved from Lichfield to Chester St John's in 1075, and upgraded St John's to cathedral status (Lichfield was the ecclesiastical centre of the Kingdom of Mercia since 669). He died in 1085 and was succeeded in December 1085 by Bishop Robert de Limesey who moved the bishop's seat to Coventry circa 1102, whereupon St John's became a co-cathedral. Ormerod states that the Domesday Book reports devastation at Tarvin and suggests that this might have arisen due to a stand being taken at Tarvin as the Normans advanced on Chester. The adjacent manor of Barrow, with 8 ploughlands, is listed as having William Son of Nigel as its Lord. Barrow later came to fall within the parish of Tarvin, and was described as a 'free chapel within the prebend of Tarvin' until the 16th century, some time after which it became a separate parish. Although Tarvin was within Rushton Hundred at the time of the Norman conquest, from the end of the 12th century over a prolonged period there was a reorganisation of the hundreds associated with the formation of Lancashire, and transfer of some hundreds to Wales (Atiscross, Exestan, and part of Dudestan), and Tarvin became associated with the Eddisbury Hundred. The hundreds of Cheshire from this time were Broxton, Bucklow, Eddisbury, Macclesfield, Nantwich, Northwich and Wirral. Apart from
