Fenton, in 1811, describes the island, and its neighbour Ynys y Cantwr: In 1903, the S.S.
Graffoe (a 2,996-ton
steamship bound from
Glasgow to
Montevideo with 3,800 tons of coal) struck Ramsey Island and sank at the northern end of Ynys Bery. The
wreck lies at a depth of 15 metres, and is one of many Pembrokeshire wrecks popular with
divers. ==Geography==
