Aschetil

Norman form of ÁSKELL or ÁSKETILL.

"The masculine name Áskell, Ásketill is found in Old Danish as Askil or Eskil, in Old Swedish as Askel and Æskil, and in Old West Norse as Áskell... Other Danish sources have Eskil, Æskil, and the Latinized forms Eskillus, Eschillus, Esquillus. Found frequently in Swedish as Æskil. This name was also one of the most common Scandinavian names in Normandy, as Achitil, Anchitil, Aschitil, Anschitil, Achetil, Anchetil, Aschetil, Anschetil and Latin versions of all of these ending in -us. Because of the popularity of the Norman name forms, variants are frequently found in post-Conquest British sources, however Anglo-Scandinavian forms predating the Conquest also appear: Asketel, Askytel, Aschil, Aschil and others."
