As far as I can ascertain all (or at leastalmost all) of the early Carrolls who settled in the Piedmont area of NC and SC including York are of the Scotch-Irish branch of Carrolls who mostly migrated from around Chester Co PA down the Catawba Trail between about 1730 to 1760. A good website for York Co. Carrolls can be found at the Downing/Carroll Kinfolk Website.
