The collection comprises property in p's Oswestry, Bishop's Castle, Shropshire, Wrexham, Gresford, Ruabon, Holt, Llangollen, Llandysilio-yn-Iâl, Llanarmon-yn-Iâl, Llandegla, Llangedwyn, Llanrhaeadr-ym-Mochnant, Llanarmon Dyffryn Ceiriog and Llansilin, co. Denb., Llansanffraid-ym-Mechain and Pennant, co. Mont., Bangor Is-coed, co. Flint, and Tilston, Cheshire. The pre-1897 Llangedwyn estate rents (the estate of Lady Williams Wynn) are not contained in separate volumes as below, but, rather, with other estate rentals in the series of Farm and Cottage receiving rentals. After 1911 (RD29), the Llangedwyn rents re-appear in those rentals. Some additional properties are included in the Llangedwyn rentals from 1897 onwards as a result of the transfer of certain properties from the Wynnstay and Ruthin estate to the Llangedwyn estate. Llangedwyn rents will also be found in the series of general rentals (see Farm and cottage rents, 1863-1898). The Llangedwyn rentals are half-yearly, ending either at Lady Day or Michaelmas. Cynllaith Owain chief rents, consisting of property in t's Lloran and Priddbwll [p. Llansilin], co. Denb., are also included from 1898 (RD4). However, since these chief rents were collected yearly, at Michaelmas, they will only be found in the Michaelmas volumes. Details of Cynllaith Owain chief rents before 1898 will be found in the general rentals, and in the series of Tithe, chief and fee farm rentals.
