   The Anglo-Saxon thanes were in all respects the predecessors of the Norman barons. The title of thane seems to have supplanted that of gesith, which appears only in the earner Anglo-Saxon laws, a denomination that may originally have designated the attendants or companions of the king, and whose wergild being triple that of the simple freeman, were, therefore, denominated not only gesithcund men, but six-hynde men. 1845, Johann Martin Lappenberg, translated by Benjamin Thorpe, A History of England under the Anglo-Saxon Kings, published 2004, page 317
