Burdett was the brother to my greatgrandfather Thomas J. Williams. Do you live near Franklin? I have been there and made pictures of the graves in Mountain Grove cemetery. We hiked to the top of a mt. near the church where my greatgrandfather is said to be buried. You can tell there are graves there because of stakes drove in the ground. There is only one marker and it is for Emma Williams, 1st wife of John Birdett Williams who was my great uncle. My email address is peggy_padilla@yahoo.com if you wish to correspond directly.
