Why are you calling him “Black” he was a Lenape Indian. I though El’s and Beys didn’t use color to describe people but their nationalities instead. He also helped design Philadelphia where he was born. He and John Hanson were also present at the signing of the Declaration Of Independence because it was taken from the Iroquois Confederacy and he and Hanson helped them create the new American colonial government using there own laws and customs. He also sued the new government for lands stolen from his people and it is contained in the congressional record.
