Thanks for the tips. $4M was promised to the project: https://twitter.com/CMMathieuEugene/status/1458893021760696324. I will study up on the definitions and circle back.

Hello again. I should have included this: https://www1.nyc.gov/site/hpd/services-and-information/fabg.page

There is evidence that people are buried there _now_. There is a movement surrounding properly honoring the site today in the present. I will take a look at the historical site you mentioned and check into how OSM views local knowledge.

A community group is working to get the site officially recognized: https://www.flatbushafricanburialground.org/africanburialgroundpast
