Administrative/Biographical history: The Mostyn family of Talacre, Llanasa, Flintshire, were a Catholic family descended from Piers Mostyn (Piers ap Richard ap Hywel, d. 1580), third son of Richard ap Howel (d. 1539) and Catherine, daughter of Thomas Salusbury of Lleweni, Denbighshire, and younger brother of Thomas Mostyn of Mostyn. Piers's son, William Mostyn (d. 1605), acquired by his marriage to Anne, daughter of Henry ap Thomas ap Harry of Greenfield, the lands of Basingwerk Abbey. William's great-grandson, Sir Edward Mostyn (b. c. 1628) was created a baronet in 1670. Francis Edward Mostyn, fourth son of Sir Pyers Mostyn, 8th Bart, was vicar apostolic of Wales in 1895, bishop of Menevia in 1898, and from 1921 onwards, Roman Catholic archbishop of Cardiff. Basingwerk abbey remained in the hands of the family until 1923, when Miss Clementina Mostyn placed the ruined abbey under the guardianship of the Office of Works (now CADW). The end of the Mostyn connection with Talacre came with the deaths of Sir Pyers Mostyn, 9th Bart, in 1912, and Sir Pyers Charles Mostyn, 10th Bart, in 1917, aged 21, which compelled the trustees to sell the mansion and estate in 1919. The estate was advertised for sale as 'A noble castellated stone built mansion, containing 40 rooms, with a handsome private chapel, and Home Farm'. It consisted of 150 cottages, 64 small holdings, licensed houses, 23 fair sized farms, numerous lead mines, a limestone quarry, and the Point of Ayr Colliery, comprising nearly 3,600 acres. According to the 1873 return of owners of land, Sir Pyers Mostyn of Talacre, baronet, owned an estimated 4,184 acres, all in Flintshire, with an estimated annual rental of £10,659.
