I'm not related to the Powell family that I know of (so far) but my ggg-grandfather was Anderson Norris b. 1807 in Edgefield. I found this deed abstract from a collection of deeds in Edgefield book #41:
Rolen Powell, Mary Powell, Reason Powell to Anderson Mitchell. Power of Attorney. For good causes and considerations the Powells appoint Anderson Mitchell of Edgefield District their attorney to receive of the estate of Emilia Powell deceased late of Edgefield District and in their names to give receipts therefor. 16 January 1826. /s/ Rolen Powell, /s/ Mary (x) Powell, /s/ Reason (x) Powell. Wit.: /s/ vardy Woolley, /s/ Anderson Norris.
Proven by Vardy Woolly 16th January 1826. George Sawyer J.P. Recorded 12 February 1826.
