Henry I., the chief of which was Botreux's Castle; by contraction, Boscastle; and that the family were Norman, and doubtless came from Les Bottereaux, near Evreux. Others derive the name from bo-treaux, the castle on the sea, or the castle on the water. As a Cornish-French compound (bor-ar-eaux), the name would translate "the dwelling upon the waters." Botterell, Bottrall, Bottrell, and Botterill, may be the same name, or from the same root.
