For we have seen a French geography-book in which Côtentin was explained to mean the land of coasts; the peninsular shape of the district gave it "trois côtes," and so it was called Côtentin. We cannot parallel this with the derivation of Manorbeer from "man or bear"; because this last is at least funny, while to derive Côtentin from côte is simply stupid.
It stood a five days' siege from Cromwell, and its shattered ruins, with the keep on the summit of the hill, show a strong fortress. From the top there is a magnificent view of the neighboring shores and far across the sea to the lofty coasts of Devonshire. Manorbeer Castle, belonging to Lord Milford, is near Tenby, and is considered the best structure of its class in Wales.
At the division of the paternal estates Bledri inherited, as his share, lands ranging along the right bank of the lower Towey, and the coast of South Pembrokeshire, extending as far as Manorbeer, the birthplace of Giraldus Cambrensis. Thus, in 1113 the Brut-y-Tywysogion mentions his name as ally of the Norman knights in their struggle to maintain their ground in, and around, Carmarthen.
