Kidwelly

The Marcher lordship of Kidwelly on the coast between the Tywi and the Loughor, with the castle and the borough founded under Bishop Roger of Salisbury.

The Lord Rhys took Kidwelly in 1159 and again held it in the 1190s; after his death it passed back to the Anglo-Normans. Carnwyllion, the commote round Llanelli, is a raiding ground where Maredudd ap Rhys will be killed in 1201. The family also holds Ogmore in Glamorgan.
