In the 1880 census of District 3 of Union County (formerly Grainger Co) Tennessee, there is listed a Pleasant Cook, age 67, and his wife Sarah Cook.Living at the home is Rebecca Nicely, noted as a sister-in-law.Also, there are two young boys noted as grandsons.They are Jacob Yadon, age 6 and John L. Yadon age 4.Both of their fathers are noted as born in Kentucky, and their mothers as born in Virginia. I am trying to find out who their parents are. I am descended from the Yadons, Cooks and Capps of Grainger County. I am also interested in exchanging information with anyone who knows how the Cooks of Grainger County, TE and Pike Co., Illinois, fit together. HELP!
