Cemais

Cemais was a marcher lordship on the north Pembrokeshire coast, with its seat at Newport. In 1326 it passed from the FitzMartin family to Joan and James Audley; their son James, second Baron Audley, held it in 1337.

The Audleys held Cemais until 1497, when the seventh baron was executed for rebellion against Henry VII. The English barony was restored in 1534, and the Laws in Wales Acts of 1535 to 1542 made Cemais a hundred of Pembrokeshire.
