There is nothing on the Internet for a Button Holler, Kentucky. There is a Butcher Hollow, Kentucky that is located in Boyle County. Have you tried to contact someone that works at Boyle County or the Kentucky Archives to see if they might be able to help you?
Thank you. I did find Butcher Haller (hollow), but my g-mother says she was born in Button Hollow, KY, Boyle County KY. Was she right? Did it exist at one time? Maybe a local term.
