Sidney Oldall Addy, The Hall of Waltheof — X. Mythological Place-Names (1893)
“ The better opinion hitherto held is that Eccles is the genitive case of an Old English personal name Æcel, so that, if the opinion were correct, Eccleshill would be a hill once inhabited by a man called Æcel. I am not, however, aware that hills were ever named after persons, though it is possible that in a few cases they may have taken the names of the mythological or half-divine beings which arose from the worship of ancestors or chiefs, or, in later times, of the saints which succeeded those beings. ”
