My Grandmother was taken to Rocky Ford Colorado in about 1908 for her health, she had TB. She died soon after and was taken back to her home in Illinois and is buried there. I cannot find a record of a death certificate for her in Colorado. I have contacted the State, County and City with no success. I recently contacted the local library and they are going to check the local newspaper. Any suggestions where I might find a death certificate for her?
Check with r/genealogy--they're the experts on hunting down things like this.
You may have tried this already, but a local (county/town) historical society might be able to help.
