Do you know of Thornhill ???

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

Our sources for Thornhill (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 Thornhill other than they indicate that Thornhill would be found somewhere in Allegheny County, Pennsylvania.

From the Blevins / Hellbock List: The post office opened  in 1872 and closed  in 1906.

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>If we encounter the name of what might be a community, our methodology is to add that name to our Gazetteer as a placeholder. As we find more information about that community, it will be added to our Gazetteer.

Just as a reminder: Our definition of a community is rather broad and includes those places (or areas) where several families lived and had a name which identified that place. For example, you might hear somebody say that they are going over to Bird Creek to see Pete ... Bird Creek is just a gas station and a couple of homes at the crossroads. While it might not be on the map, everybody in the area knows it by that name.

Places of interest include buildings at a crossroad, several families clustered in a hollow or maybe the location of a way station. It also includes places like mines, lumber camps, ferry crossings, etc. The community might still exist, is now gone or only existed for just a short period of time.

Also keep in mind that Thornhill could have been on the original document by mistake, misspelled, the original/alternate name of a community that we've listed elsewhere or was placed in the wrong county. Sometimes a post office or train station would have a different name than the community where it's located, so two names might be referring to the same community - we're working to straighten it all out.
