Biographical history

The Brogyntyn estates were managed by a succession of agents: Anne Jones at Clenennau during the last two decades of the seventeenth century; Henry Griffith during the first part of the eighteenth century, followed by a pair of notorious brothers, Griffith and John Parry. Thomas Williams at Nant at the end of the seventeenth century; John Jones for Brogyntyn (Porkington) during the 1760s-1770s; William Heighway for Abertanat; and Wiliam Fetherston Haugh in Ireland, 1840s-1850s. A rental of c.1677/8, drawn up after the death of William Owen, states the total of rents in Shropshire and North Wales to be £1324, with additional income from wood, leases and estate improvements. Over the next two centuries the estate greatly increased, so that by 1883 the family's land holdings in North Wales, Shropshire, Berkshire and Ireland were worth £26,000 a year. Even so, accounts and letters of the eighteenth and nineteenth centuries present an impression of neglect, corrupt agents and tenants unable to pay their rents.

Notes area


The rentals and accounts appear to be remarkably unsystematic; some of them cover single estates, while others deal with several estates together. The lack of consistency has influenced the cataloguer's decision to list the administrative records in groups of estates, rather than individually, to avoid an excess of cross-references.
