In his marriage settlement the 4th Baron Arundell had settled Trerice and his other estates including Efford and Bude in Cornwall, and Selworthy and Luccombe in Somerset, in default of his own issue, on his wife's nephew, William Wentworth (died 1776), a gentleman usher of the privy chamber to Augusta, Princess of Wales, son of Elizabeth's other brother Peter Wentworth of Henbury, Dorset, and in default of his issue with remainder to "Sir Thomas Acland, Baronet" (Sir Thomas Dyke Acland, 7th Baronet (1723–1785)) and his heirs. William Wentworth duly succeeded to the estates under the settlement, and by his will dated 1775 resettled the estates on his own son Frederick Thomas Wentworth, 3rd Earl of Strafford (1732–1799), with remainder on failure of his issue, to the 3rd Earl's sister Augusta Anne Wentworth (died 1802), wife of John Hatfeild Kaye (1731–1804) of Hatfeild Hall, Stanley, West Yorkshire, and on failure of issue from both, (which was the event) to Sir Thomas Dyke Acland, 7th Baronet (1723–1785) and his issue. Following the death of Augusta Anne Kaye in 1802 without issue, Trerice and the other former Arundell estates passed to Sir Thomas Dyke Acland, 10th Baronet (1787–1871), grandson of the 7th Baronet.
