a bookseller of London. He was born in Steeple, Dorset, of a branch of an old Dorsetshire family. Clavell was the author of a curious little treatise entitled His Majesties Propriety and Dominion on the British Seas asserted: together with a true Account of the Neatherlanders' Insupportable Insolencies, and Injuries they have committed; and the Inestimable Benefits they have gained in their Fishing on the English Seas: as also their Prodigious and Horrid Cruelties in the East and West Indies, and other Places. To which is added an exact Mapp, &c., octavo, London, 1665.
