Penboyr
Penboyr is a hamlet in the county of Carmarthenshire, Wales consisting of a number of houses, smallholdings, farms and a church. About
"This is a small area within modern Carmarthenshire consisting of regular rectangular fields and dispersed farms. It lies within the medieval Cantref Emlyn, in Emlyn Uwch-Cych commote. Cantref Emlyn had been partly brought under Anglo-Norman control in c.1100 when Emlyn Is-Cych commote to the west was reconstituted as the Lordship of Cilgerran. Numerous castles were established in Uwch-Cych comote - none of which has any recorded history - but the commote was back under Welsh control by the 1130s, where it remained throughout the 12th and early 13th centuries. A motte-and-bailey castle, ‘Tomen Llawddog’, was established within this character area, immediately next to Penboyr parish church, St Llawddog's; and therefore the may be contemporary. It is not known whether they belong to the brief period of Anglo-Norman control, or are Welsh foundations of the later 12th century. However, the church dedication to St Llawddog may be later medieval, when his cult was still active in the area. The church was first recorded in 1222 when it was ‘restored’ to the Bishops of St Davids, to be counter-claimed by the crown. Its early parish status, along with its close relationship to the castle, suggests that the two represent a deliberate Anglo-Norman plantation. They may therefore represent the site of a failed vill. The castle, which has no recorded history, probably become disused at an early date. They never became the focus for any later settlement, nucleated or otherwise. " Historical references
