Hi,

If you do a search of the slave narratives (available on ancestry.com) using Granville as a keyword you will find some stories of former slaves from there.

State: North Carolina Interviewee: Woods, Alex

State: North Carolina Interviewee: Lawson, Dave

State: Texas Interviewee: Blackwell, Willie
Willie Blackwell, 103, was born on the Blackwell plantation in Granville County, North Carolina.

Hope this helps,
