There were Dyers in Marshall or Lincoln Counties in late 1800s and on into l900s. My father had an uncle, John Pigg, who married two Dyer sisters. One died and he then married the other. I believe there is a little bit of info in the Biography section of Goodspeed's Lincoln County under John Pigg. That might be a slim lead for the person who is looking for Dyer info. Joyce Park Riggs
