Kenneth, I am also a Dunn (maiden name) and my ancestors settled in Polk Co. TN and Murray Co. GA. I have traced my family back as far as Daniel Dunn who came from VA and settled in Greene Co and then Blount Co. TN. My gg-grandfather, Daniel Richard Dunn (married Millie Lawson) left Blount Co. and settled in Murray Co. when the govt. opened up that land. He and Millie had numerous children, about 15, I think. My g-grandfather was William Walter Dunn (aka Black Bill) and my grandfather was Alfred Estes Dunn, both from Polk Co. Does any of this ring a bell with you? I have never heard of your Robert Sherman Dunn but I bet we are related somhow. Jody
