William Daniel Cobb was born in Dyer, Tennessee, in 1861. By 1900, he was living in Jonesboro, Craighead County, Arkansas, and worked in the newspaper business. W. D. had a brother, Rev. J. D. C. Cobb, who also worked in the newspaper business in Jonesboro and preached at the Cumberland Presbyterian Church. I cannot tell the difference between the two, but these are the two brothers bird-hunting in Craighead County around 1915, with two fine dogs and a couple of double-barreled shotguns. Notice the split rail fence behind them.
