Castlemartin Hundred

Castlemartin was a hundred in Pembrokeshire, Wales. Initially created by the Marcher Lords of Pembroke in the 14th century from the western part of the pre-Norman cantref of Penfro, it was confirmed by the Laws in Wales Acts 1535 and 1542. The hundred, with its capital at Pembroke was early settled by English and Scandinavians, and was a centre of the Norman/English "plantation" in the 12th century. Since then it has been mostly English-speaking, and part of Little England beyond Wales.
