Cherokee Springs Hospital appears to have been in Catoosa County, GA,
the county seat being Ringgold.
I've not done research at the public library in Ringgold, but I understand it has
a nice history & genealogy department.
Here's an email address for their archivist, Connie Haney:
conniehaney@catoosacountylibrary.org
If you don't get a response, you might want to call the librarian or drop
them a letter of inquiry.
Sincerely,
Greg
