Do you know of Thermal ???

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

We found mention of Thermal as a community (see Mentions and References below), but haven't been able to determine its location - other than being located somewhere in San Diego County, California.

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 Mile's to see Pete ... Mile's 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 Thermal 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.
