Portchester Castle was defended not by a standing garrison but by a ring of surrounding manors, each owing a specific number of armed men for a specific number of days. The obligations are scattered across separate VCH parish entries for Portchester, Wymering, Cosham, Farlington, Boarhunt, Southwick, and others. No published source assembles them into one view.

Our database does. The full picture shows Portchester’s burgesses owing 12 men for 15 days in time of war. Drayton owed one man to guard the east gate for 15 days. Wanstead owed one man for eight days. Cosham owed one armed man for castle defence. Boarhunt Herbelyn owed a habergellum, a mail coat, for 20 to 40 days of service.

Mapped together, these obligations describe the defensive infrastructure of a medieval royal castle, extracted from its hinterland through tenure. Each manor profile in the database records its castle service obligation, and the network view shows all of them linked to Portchester.

Southwick Priory was founded inside Portchester Castle around 1128 and relocated to Southwick around 1150. Over four centuries it accumulated manors across both Hampshire and Sussex: Southwick, Old Fishbourne, Newlands, Moralls, Boarhunt, West Boarhunt, Farlington, East Hoe, and holdings at Widley and Wymering. By the Dissolution in 1538, the Valor Ecclesiasticus valued its income at 257 pounds 4s. 4d.

The Hampshire manors appear in VCH Hampshire, Volume 3. Old Fishbourne appears in VCH Sussex, Volume 4, published decades later. The priory’s own entry is in VCH Hampshire, Volume 2. Our database links all three volumes, connecting a charter from Turstin son of Engelram (c.1120 to 1150) that granted Old Fishbourne to Southwick with the priory’s Hampshire holdings documented in completely separate publications.

The result is the first compiled view of Southwick Priory’s full manorial portfolio, mapped, with lordship chains, across the county boundary.

In 904 King Edward the Elder granted the manor of Waltham to Bishop Denewulf of Winchester in exchange for Portchester. It is one of the earliest documented land transactions in Hampshire. The two manors sit 15 miles apart and appear in separate VCH entries with no cross-reference between them.

The database connects them. The exchange explains why the Bishops of Winchester held Bishop’s Waltham continuously from 904 until the Ecclesiastical Commissioners took over in the nineteenth century, and why Portchester was in Crown hands from the same date. One transaction in the tenth century set the tenurial course of both manors for the next 900 years.

Southwick Priory surrendered on 7 April 1538. Titchfield Abbey had surrendered the previous year. Between them they held at least a dozen manors in the coverage area. The VCH records each Dissolution transfer in the relevant parish entry. Read them together and a pattern appears.

Thomas Wriothesley, later 1st Earl of Southampton, took Titchfield, Stubbington, Crofton, West Boarhunt, and parts of Portchester. John White, a servant of Wriothesley’s, took Southwick, Newlands, Moralls, and Wyker. Anne of Cleves received Old Fishbourne. Within a decade, two men and a queen had divided between them the accumulated holdings of two religious houses that had taken four centuries to assemble.

The database tracks each chain: from monastic house to Crown to lay grantee, manor by manor.

By the early nineteenth century, the Thistlethwayte family held Southwick, Wanstead, Belanney, Newlands, Portchester, Wymering, and Widley. The VCH notes each acquisition in its separate parish entry. Assembled in the database, the scale of the accumulation becomes clear: one family had quietly reassembled much of what Southwick Priory once held, across the same stretch of Portsdown.

The sequence is traceable. The Thistlethwaytes inherited Southwick from the Norton family in 1733. Robert Thistlethwayte purchased the Rashleigh half of Portchester in 1775, reuniting both moieties of that manor for the first time since the death of Sir William Uvedale. Thomas Thistlethwayte bought Wymering in 1821. Widley followed. By the time the VCH was published in 1908, the family held the lordships from Southwick Park.
