Havelok (3 syl.),
the orphan son of Birkabegn, King of Denmark, was exposed at sea through the treachery of his guardians, and the raft drifted to the coast of Lincolnshire. Here a fisherman named Grim found the young Prince, and brought him up as his own son. In time it so happened that an English princess stood in the way of certain ambitious nobles, who resolved to degrade her by uniting her to a peasant, and selected the young foundling for the purpose; but Havelok, having learnt the story of his birth, obtained the aid of the king his father to recover his wifes possessions, and became in due time King of Denmark and part of England. (Haveloc the Dane, by the Trouveurs.)
