Rentals mainly for the Shropshire estate of Brogyntyn and the Llanddyn estate in Llangollen, Denbighshire, 1646-1849. They also sporadically include the Owen family's lands in Merionethshire and the Clenennau estate in Caernarfonshire, 1657-1696, 1768-1773. A substantial gap exists in the Brogyntyn (Porkington) and Llanddyn rentals between 1720 and 1762. From 1792 the rentals exist as separate units for each half year and they become more regular in format, to include columns of arrears and land tax payments. At the same date the name of Ellen Owen, Robert Godolphin's remaining unmarried sister, appears as joint owner with that of her brother-in-law, Owen Ormsby. From Michaelmas 1797, the rentals include property in Broniarth and Llandysilio, Montgomeryshire. The purchased estates of Oerley Hall and Drenewydd are included from 1827 and 1832 respectively. Several rentals include accounts of arrears and expenditure on labour and repairs.
