I do not know much of AR history, to be sure I looked up when it became a state - in 1836. What little I know of AR around that time, most SKINNER folk were still back in Lunenberg VA and some in NC growing tobacco and cotton. From what I can tell, a greater migration followed the civil war. Go looking at some 1850 - 1860 AR censuses to find your Skinners and who they lived near. My guess, their generations would have come through AL on their way south from the NC and VA.
