Dovie I have copies of the Arkansas Counties from 1810 to 1910 Jonesboro is in Craighead County, the County has not changed since 1870. before that the Counties were changing, and if you had people in that area you can check the census of all the surrounding counties before 1870. especially Poinsett- Green and Cross counties. Craighead was formed out of Green Poinsett and Mississippi Counties between 1850 and 1860. You can search those counties in 1850 and maybe find your ancestors. When I first started researching for my ancestors I wondered why they seemed to go from one County to another, then I found they did not move at all, the Counties came to them. hope this helps in some small way.
