Do you know of Ontario ???

This page is an orphan - a placeholder until we can discover more about Ontario. When we encounter a name that is new to us, we add it to our Gazetteer with the hope that we'll discover more information in the future. Such is the case with Ontario.

Our sources for Ontario (see Mentions and References below) indicate that it was a community with a post office by the same name. Unfortunately our sources aren't clear about the location of Ontario other than they indicate that Ontario would be found somewhere in Lenawee County, Michigan.

From the Blevins / Hellbock List: The post office opened  in 1881 and closed  in 1902.

This entry could have originated in error. It might be that a source had a misprint, was simply wrong or we made a transcription error while referencing it. Many of the documents we reference are from the 1800s and the early 1900s, with some easier to read than others.

Part of the difficulty in identifying whether a name is a post office or a community lies with how Post Offices were named. We've prepared an article with our understanding of how post offices were named: Naming of Post Offices.
