Scope and content

Rentals of the Clenennau, Glyn, Sylfaen and Ystumcegid estates, [1535x1572]-1849. They cover Eifionydd [1535x1572] and Clenennau, 1551-1689, combined with Brogyntyn, Llanddyn and lands in Anglesey from 1589 to 1606; Glyn, 1623; Ystumcegid, 1692-1723; and Clenennau, Glyn, Sylfaen and Ystumcegid, 1690-1849. Gest disappears from the rentals by 1678, which is consistent with Sir Robert Owen's loss of the township to William Price of Rhiwlas. Sir Robert married Margaret Wynn in 1683, but Glyn and Sylfaen in Merionethshire do not appear as joint property until 1690. Some of the Clenennau and Glyn properties appear collectively as the Merionethshire estates from 1727. Likewise by 1749 some of the other Caernarfonshire properties are not distinguished separately from Ystumcegid. From 1779 to 1804, the idividual properties are not identified, but the tenants' names are listed under the vague headings of 'Caernarfonshire estate' or the Merionethshire estate'. The purchased property of Dolbenmaen is incorporated from 1742 and part of the Shropshire and Denbighshire estates are included in 1773. Additions in the form of allotments and encroachments are in evidence from 1832. Several of the rentals incorporate accounts of arrears and repairs to property.
