I can't help with the Powell family but have a little info on Hardy Carroll that may be of interest. Hardy was married to Lydia Hollingsworth, dau. of Henry. 1809, Hardy purchased land adjacent to Henry Hollingsworth. 1810, Hardy sold land to Willis Carroll, witness Zebulon Hollingsworth. 1826, Estate Administration for Hardy Carroll in July Court, Duplin Co., NC. I only had one daughter for Hardy listed, Polly Carroll, married to Auston Beasley.
