Sandy, It may not be too helpful, but last year while visiting in Sumter, Lynchburg and Mayesville areas, I met some African American families.They related their ancestors had taken the name of the slave owners after emancipation.I met an Ed Lowry, who was over 90 years of age still living on land given to his ancestors by James Lowry at the end of the war.Also a Samuel Lowry whose ancestors had attended Old Brick Church;they were probably among those who started the Goodwill Presb. Church.
I haven't done much research yet, but there was a Jacob Wooters WHEELER in the area during those early years, whose daughters married a Lowry and WILSON.
I am not African American, but did this research on my husband's families. There were several names of slaves listed in their wills; they may have taken their names from the slave owner.You might get a clue;sorry I can't be more helpful.
