The Turbervilles of Bere Regis could trace their descent from Sir Payn de Turberville, who came out of France with the Conqueror and was granted the lordship of Coity in Glamorgan by William Rufus. From the 1240s the main Dorset branch was seated at Bere, where they held the hundred as well as the manor by grant of the earl of Pembroke,
William’s mother Margaret, who survived her husband, continued their long-running dispute with the abbess and convent of Tarrant, the Turbervilles’ neighbour at Bere. At an assize of novel disseisin of 1414, the abbess had successfully brought an action against Sir Robert and Margaret with five other members of their family, including the young William, whereby she had recovered possession of some 650 acres of land and a moiety of a fulling mill, which she claimed had been granted to the abbey by Henry III.
Through his first marriage, contracted early in the 1420s,
Turberville attested the shire elections held at Dorchester on 26 Mar. 1425, when Sir Richard Stafford* and John Newburgh I were returned. Both men appear to have been connected with the administration of the Dorset estates of Edmund, earl of March, who had recently died, and Turberville may have been associated with them in this regard, for four weeks later he was a member of the jury called to give evidence in the county town at the earl’s inquisition post mortem.
Another reason for Turberville’s exclusion from public office may have been the aggressive renewal in the 1430s of his family’s quarrel with the abbess of Tarrant, who protested about his usurpation of her rights of jurisdiction at Bere, and the way his servants had wrongfully levied tolls and imposed fines on her tenants. In 1435 she brought further pleas of trespass against him, alleging that over the previous 11 years he had wrongfully had hundred courts conducted at Bere in his name, and had made a forcible entry into her property in the local forests, causing damage to the sum of £50. A jury at the assizes held in Dorchester in 1438 found in her favour, upholding her claims that the hundred and its court pertained to the abbey, which was also entitled to other privileges which Turberville had usurped. Damages of £100 were awarded against him. However, as it was found that the abbess had falsely accused him of trespass and he was acquitted on this particular charge she remitted the damages to him.
Turberville did not lack for important connexions among the gentry of the shire. He was called upon to witness deeds, and acted as a feoffee for the prominent family of Newburgh, from which he selected his second wife.
Turberville himself died earlier the same year, on 5 July. It is possible that like William Stafford*, another member of the Dorset squirarchy who died just 12 days before him, he met his death while engaged in combating Cade’s rebels in Kent. The executors of his will, which has not survived, were his widow Edith and her brother John Newburgh II. Turberville’s heir, John, the eldest of his four sons by his first wife, and then aged 28,
