Lam-Goemagog. The legend is that Corineus (3 syl.), in his encounter with Goemagog, or Gogmagog, slung him on his shoulders, carried him to the top of a neighbouring cliff, and heaved him into the sea. Ever since then the cliff has been called Lam-Goemagog. (Thomas Boreman: Gigantick History; 1741.)
