Capel St Tomos was reputedly one of five chapels of ease serving Kidwelly parish, the other four being named as Llanfihangel, Coker (NPRN 31584), Cadog and Teilo (NPRN 417692). The cemetary occupied a field to the north of Kidwelly, which was still known as Mynwent Domos in the early 20th C. Human remains are known to have been disturbed in adjacent gardens in the 19th century. It is assumed that the chapel building was located either within, or adjacent to, the cemetary.
