Monarch and Monarch Mill are two names for the same Buffalo-area mill village cluster and are kept as separate entries because both appear in local use; Lockhart and Lockhart Junction likewise name the town proper and its former rail junction a short distance away, not the same point on the map.<\/p>\n
