A volume originally containing fifteen indexed manuscript maps, with acreages, of the Dolwilym estate in the parishes of Llanglydwen, Llandysilo, Llan-gain and Llanboidy, Carmarthenshire, and Narberth, Pembrokeshire, surveyed by Alfred Thomas, 1816-1834. The estate belonged to E. G. Protheroe before it was acquired through marriage by the Beynon family. Three maps of farms in the parishes of Llangoedmor, Cardiganshire, have been cut out (between ff. 30 and 31) and a map and acreages of Glyn-taf farm, Llanboidy, 'surveyed by R. Jones 1795, corrections made up to 1840' have been added (ff. 37-9).
