North Carolina's largest black slave holder in 1860 was named William Ellison.

William Ellison was a very wealthy black plantation owner and cotton gin manufacturer who lived in South Carolina (not North Carolina). According to the 1860 census (in which his surname was listed as "Ellerson"), he owned 63 black slaves, making him the largest of the 171 black slaveholders in South Carolina

American Indians owned thousands of black slaves

Miles places the number of enslaved people held by Cherokees at around 600 at the start of the 19^th century and around 1,500 at the time of westward removal in 1838-9. (Creeks, Choctaws, and Chickasaws, she said, held around 3,500 slaves, across the three nations, as the 19th century began.)

In 1830 there were 3,775 free black people who owned 12,760 black slaves.
