Do you know of Coryell Islands ???

This page is an orphan - a placeholder until we can discover more about Coryell Islands. 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 Coryell Islands.<1>

We found mention of Coryell Islands as a post office (see Mentions and References below), but can't determine its location - other than being located somewhere in Mackinac County, Michigan.

It's common that the post office is named the same as the community in which it's located (although that's not always case). In this case, we can't match this post office to any of the existing communities in our gazetteer.<2>

From the Blevins / Hellbock List: The post office opened in 1925 and closed in 1958.

Footnotes ...

<1>	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.
<2>	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.
