Administrative/Biographical history: The Price family of Penllergaer,Glamorgan, the original owners of the estate, descended from John Prees and his wife Elizabeth. Their son, Griffith Price married Elizabeth, daughter of Thomas Llewelyn, of Ynis-y-gerwn, also in Glamorgan. Their great-great grandson Griffith Price died without issue and devised the estate to his cousin, John Llewelyn (d. 1817) of Ynis-y-Gerwn.
The Llewelyn family settled at Ynis-y-gerwn following John Llewelyn William Llewelyn's purchase of the estate. On his death in 1630 the estate passed to his brother and heir, Thomas Llewelyn. His great-great grandson, John Llewelyn (d. 1817) inherited Penllergaer on the death of his cousin. John Llewelyn's daughter, Mary, married Lewis Weston Dillwyn (1778-1855) of Burroughs Lodge and Sketty Park, Glamorgan, who had been appointed by his father to manage the Cambrian Pottery in Swansea at the beginning of the nineteenth century.
Lewis and Mary's son John Dillwyn-Llewelyn (1810-1882) assumed the additional surname of Llewelyn. He was succeeded by his son Sir John Talbot Dillwyn Llewelyn, 1st Bart who was in turn succeeded by Sir Charles Leyshon Dillwyn-Venables-Llewelyn, 2nd Bart (b. 1870) of Penllergaer, Ynis-y-gerwn and Llysdinam, He married Katherine Minna (b. 1870), daughter and heiress of Richard Lister Venables (1809-94) of Llysdinam, Montgomeryshire. Sir Charles assumed the additional surname of Venables in 1893.
