The pedigree of the family up to the year 1588 is given by Lewis Dwnn (Visitations, i, 44-5), based, probably, on tables compiled by Thomas Jones (c. 1530-1609), Fountain Gate, Tregaron (q.v.); see also the pedigree in Pen. MS. 156 as printed in West Wales Hist. Records, i, 3-4. As details for subsequent generations are given in Burke, T. Nicholas, Annals of … County Families of Wales, i, 207-9, and in other works there is no need to enlarge on all the members of the family or of its branches in this article.

JOHN PRYSE, grandson of Rhys ap David Lloyd and barrister at law, was a member of the Council of the Marches, and represented Cardiganshire in Parliament at various times between 1553 and 1572. His will was proved on 7 Dec. 1584. He had m. Elizabeth, daughter of Sir Thomas Perrot, of Haroldston, Pembrokeshire (see the article Perrot) — see ‘Cywydd i Siôn Prys o Gogerddan’ (with a reference to Elizabeth) by Owain Gwynedd in Cwrtmawr MS. 12 — and by her was the father of Sir RICHARD PRYSE (knighted 1603), who had been admitted to the Inner Temple, Nov. 1584. Sir Richard Pryse, who was high sheriff of Cardiganshire in 1604, and represented the county in Parliament on three occasions, d. in Feb. 1622/3, and was succeeded by his son, Sir JOHN PRYSE, who had been admitted to the Inner Temple, Nov. 1608, and was the father of Sir RICHARD PRYSE (d. 1651), 1st baronet of Gogerddan (created 1641). He was Member of Parliament for Cardiganshire, 1646-8. He m. (1) Hester, daughter of Sir Hugh Myddelton, bart (q.v.), and (2) Mary, widow of Anthony Van Dyck, the well-known painter. He was succeeded by his son, Sir RICHARD PRYSE, 2nd baronet, who, in turn, was followed by his brother, Sir THOMAS PRYSE, 3rd baronet. The 3rd baronet was succeeded, in 1682, by his nephew, Sir CARBERY PRYSE (d. 1695), 4th baronet, who figures in D.N.B. During his time (c. 1690) mines were discovered on his estate, at Bwlch yr Esgair Hir — the ‘Welsh Potosi’ mines as they came to be called. For various reasons, given in D.N.B. and the sources named therein Sir Carbery Pryse discovered that the company which he formed to work the mines was not destined to prosper to the extent that had been expected, and when he d., in 1695, the company was greatly in debt. After his death, Sir Humphrey Mackworth (q.v.) acquired his shares. As Sir Carbery died unmarried, the baronetcy expired, the estates devolving upon EDWARD PRYSE and afterwards upon LEWIS PRYSE (1684-1720), Member of Parliament for Cardiganshire and for the Cardigan borough. As Lewis Pryse left no son — he had m. Ann, daughter of John Lloyd of Aberllefenni — the property went to his cousin, THOMAS PRYSE, Member of Parliament for Cardiganshire, 1741-3, whose only son, JOHN PUGH PRYSE, represented both Cardiganshire (1761) and Merionethshire in Parliament (for references to him, and to his mother, Maria Charlotte Pryse, see the Schedule of Rug Muniments in N.L.W.). John Pugh Pryse d., unmarried, 13 Jan. 1774, and was succeeded by his cousin, LEWIS PRYSE (1716-1779), of New Woodstock, Oxon., whose daughter, MARGARET (PRYSE), m. EDWARD LOVEDEN LOVEDEN, of Buscot, Berks. — whence the presence of Buscot documents among the Gogerddan muniments in N.L.W. (N.L.W. Annual Report, 1948-9).

The heir of Margaret (Pryse) and Edward Loveden Loveden was PRYSE PRYSE (1774-1849), whose grandson, Sir PRYSE PRYSE (1838-1906), became the 1st baronet (created 28 July 1866) of the present line. ‘Plas Gogerddan’ and much of the estate was acquired by Aberystwyth University College in Aug. 1950.
