The will abstract is so unusual because it does list all of the slaves and relationships in such detail. The actual will must be extremely long if this was considered an abstract. I was checking around the County webpages to see if any copies of the wills were posted, but they aren't. I know we've been trying to add more African American records to the websites, and there are a couple of projects going on right now, but I don't see anything on this one. I agree, though, that the William Eaton Papers are probably a good place to check, I see that it does seem to have quite a collection of records for them. The EATON family was involved in a lot of history for the early NC counties and the first William Eaton who lived in Granville in the mid-1700's was an important figure in regards to many of the Free Colored People of the area, too.
The Manuscripts Dept. at Chapel Hill is a terrific resource for AA research because they hold many of the records of the North Carolina slaveholders, and the records for some of them can be quite extensive. As a matter of fact, I found records of my entire WILLIAMS family who were slaves in Warren County in the Annie Blackwell Thorne Collection, which consists of records of the WILLIAMS, ALSTON, KEARNEY, & DAVIS families of the County. I have often encouraged people to check those out if they could because the family kept such good records of their slaves, including births, deaths, etc. and who was who of each of their slaves.
One other thing, while I was checking on things about EATON, I came across an interesting website that could be of interest because it about some of the slaves of the EATONs. It's entitled: "Infectious disease among enslaved African Americans at Eatonís Estate, Warren County, North Carolina, ca. 1830-1850"; here is the link:
