Vacation rentals in Ninemile

I want to make sure the blurb is accurate, but I can’t find reliable, specific information about a town named Ninemile, Tennessee. It may be an unincorporated area or a spelling variant (e.g., Nine Mile) in another county. Could you share the county or a nearby city, or confirm the spelling? Once I have that, I’ll craft a precise 2–3 sentence blurb for your vacation rental page.
