Thank you for posting this excellent article, Jack. If there is anyone who isn't able to access the article behind the paywall, the US Black Heritage Project has two more brief articles on the Shockoe Hill Burying Ground available on our "African-American Resources for Virginia" page found here:
https://www.wikitree.com/wiki/Space:African-American_Resources_for_Virginia under the "Resources by Location: Independent Cities" heading for Richmond, Virginia.
This burying ground is on our list for profiles to be made for those who were buried there. Our project members and recently formed USBH state teams are hard at work documenting the millions of people who were enslaved and their descendants, and if this interests anyone, we would love to have your help. If you find one without it, please add the {{African-American Sticker}} to the top of the profile of any Black person living in the United States, so that the project can keep track of the profiles and honor their heritage. If you'd like to be more involved, please consider joining the USBH Project:

We have state teams for Florida, Georgia, South Carolina, and Virginia (with teams coming soon for Louisiana and Texas), if anyone is interested in working in a particular state, and we also have teams working country-wide in different areas such as profile improvement, African-American notables, Heritage Exchange (slavery, plantations, and more), and Family Builders (finding and connecting enslaved ancestors with descendants), and more. Every team needs more help, so if you have an interest, please consider joining the project and letting us know which particular area or areas you are interested in.
