I stumbled across this site today, and it might come in handy for other researchers out there.
This site is great to find places that no longer exists, or it is a very rural/small place, maybe a mountain or a stream, a cemetery or other geographical places.
It is an official site, so the link might actually be a permanent one in my lifetime…
From their site:
The U.S. Board on Geographic Names is a Federal body created in 1890 and established in its present form by Public Law in 1947 to maintain uniform geographic name usage throughout the Federal Government. The Board comprises representatives of Federal agencies concerned with geographic information, population, ecology, and management of public lands. Sharing its responsibilities with the Secretary of the Interior, the Board promulgates official geographic feature names with locative attributes as well as principles, policies, and procedures governing the use of domestic names, foreign names, Antarctic names, and undersea feature names. «
