Just to clarify....No enrolled militia except for the immediate pre-secession times 1860 etc. Very few counties actually fielded militia until the growing conflict appeared and the 1860 militia's began forming. Otherwise, any were social in nature. That is why the governors had to put out calls to the counties to raise militia in order to send to Oklahoma border, Mexico etc., there were no standing militia's around.
I do know there is a listing of all officers from the counties at the Ark History Commission, but not the actual muster rolls of the men. It covers from the 1820's until the 1862 last roll you mention. Too bad the men's names are not found anywhere.
