This Member’s family traced their pedigree back to Bleddyn ap Maenyrch, king of Brycheiniog (Breconshire) at the time of the Norman invasion, and to Dafydd Gam, a hero at Agincourt.
In around 1617 Prise married Mary, daughter of Gregory Prise†, his great-uncle. Through Gregory, Prise’s father had already acquired over 3,000 acres in Herefordshire.
Prise was returned for the county in 1626. Normally the knighthood of the shire was bestowed on a Member of the Williams family of Gwernyfed, but during the mid-1620s there was a hiatus in their representation, creating a temporary vacuum into which Prise either jumped or was pushed. The Williamses presumably gave Prise their blessing: Prise’s father, after all, was an ally of the Gwernyfed family, and in 1631 would help witness the key marriage contract of Henry Williams*.
Following the death of his first wife, Prise married again. In 1631 he took as his new wife Anne, daughter of Sir George Chute and heiress to Wistaston, Herefordshire. He and his father subsequently moved to Wistaston and settled most of the family’s Breconshire lands, worth some £300 p.a. and including The Priory in Brecon, on the Member’s younger brother, Herbert.
Prise’s estate was sequestered in 1649, although his wife claimed a fifth share as the Wistaston properties were held by her. A fine was set at £431 11s. 8d., half of which was paid by Prise’s father. The latter died in 1654 after settling the estates on Prise’s son, also named Thomas†, whereupon Prise’s wife, Anne, informed Lord Protector Oliver Cromwell* that her son was a minor and that his trustees had declared they were powerless to raise the outstanding half of the fine; it is unclear whether this sum was ever paid. The composition proceedings revealed that Prise was indebted to his father-in-law to the tune of £1,200 for rent arrears due before 1640, while the administrators of the Exchequer Baron Thomas Gates clamoured for repayment of a debt of £500.
Prise seems to have held little or no land in his own right at the Restoration, possibly because he was then attempting to evade payment of a longstanding debt of £700, incurred after borrowing £350 in 1648 from William Bold.
