Pretty Certain
レトラッド: Leitorado (Portuguese for 'Reader')

Maybe?
ルース街道: Luce ('Light') or Rhoose (Southernmost seaside settlement in Wales, kinda matches location-wise) ムース: Muse, and not in the Princess Proto Scherazard sense メルへローズ: Marché Rose (French for 'Pink Market', there's an actual one in Bamako, Mali) [doesn't quite match the katakana] シュルフ: I've seen this used in Japanese for both Schluff ('Silt' in German) and Scholz (German name). I'm rather leaning to the latter エキュル: Écru (French for 'Unbleached/Raw'), also found several towns named Herque(ville) which have been rendered in Japanese with the same katakana オースタン: Ostern (German for 'Easter', with some juicy if disputed origins) エネド: Ened (Old English for 'Duck', it's a seaport)
