Land and Property

Details of extant records on Archives Network Wales for the following;

  • Llanblethian (The Causeway) deeds   1715-c1900         "The row of houses known as Causeway Cottages stands on land which was in the possession of David Tristham in the 1690s. When the current cottages were built is uncertain, but they appear in the 1841 census enumerator's returns. Despite the proximity of the cottages to the former Llanblethian woollen factory, there is no evidence to suggest that their owners or inhabitants had any direct connection with the weaving industry. The row seems to have been built as accommodation for artisans and agricultural workers"
