I'm assuming you want information about Nancy and John's other children, so here's what I have:
Jesse Cooper, b. 1843 in AR; Asa Cooper, b. 1846 in AR; Sarah J. Cooper, b. 1849 in AR; Mary Cooper, b. 1850 in AR; Ann E. Cooper, b. 1853 in AR; Martha Cooper, b. 1856 in AR;and Vashti Cooper, b. 1858 in AR.
All dates are approximate. Sarah was supposed to have been half Irish and part Indian. She was dark skinned, had red hair and some slight freckles.
This information comes from Carl Dollarhide, Jr.'s book, Descendants of Asahel Dollarhide.
That's all I have on the Coopers. I do have quite a bit more on Nancy's brothers and sisters.
