I believe I may have a connection to your Adcoxes and Adcocks of Robertson Co. TN, however it is earlier. My husband's great-grandmother was Perlexna Lynn Adcox (we think, but it may be Adcock). She was born im Davidson Co. TN in 1844. Her father was Henry Adcox of Robertson Co., born in 1812, and her mother was named Elizabeth, reportedly born in Virginia in 1815. Henry died in Ridgetop (Roberson) in 1880. I would be happy to exchange information.
