I am also researching Bingaman in Arkansas. Bingaman was my grand mothers maiden name. I found a Dove Rhoden age 17 married a John Bingaman age 37, 9-27-1885. My ancestor was James K. Polk Bingaman born about 1856 in Heber Springs, Ark. and later wound up in Missouri. John was married in Carroll county. Thats all I have.
