:::::::  It is not appropriate for Wikipedians to look at two maps and say "this old map has X name so that must be a previous name for this settlement."  
 :::::::  I can see "near", not "on the site of". Really, for that we need a text source which says that. 
 ::::::: Scoobydunk: it is a violation of WP:OR to look at a map, or multiple maps, and draw conclusions from them. 
 :::::::  drawing your own conclusions from looking at maps is a violation of WP:OR 
 ::::::: It really does not  get any clearer than this, I don't care how long you've been editing. Perhaps it's time to actually read and understand Wikipedia policy after all this time. If you continue it is you who will be topic banned.
