Hello Bob Trapp Per your message inquiring about Pidgeon or Pigeon Roost Tennessee here is what I found out. Pidgeon Roost had a post office from 1827 to 1832. It was moved to a commuity called Mt Vista apparently in 1832. It is my understanding that these two locations would have been in what is now Henry County Tennessee which is on the Northern border of Tennessee and Kentucky. I think, but am not sure, that the County seat for Henry County may be Paris, TN. Hope this is of help to you. Ed Pigeon Forge, TN
