I, too, am researching Caleb Cox's ancestors. I have quite a lot on Sylvesters and Thomas Cox family also. Caleb (known as Cale) was my great grandfather. There are so many Coxes in Arkansas and Missouri, but Caleb, Thomas and Debby don't seem to belong with any of them, even tho Thomas and Debby's families are listed next to William Cox's family in the 1840 Sevier County AR census.
