Although I have not been able to find officials documents reporting the internment of African American veterans at Bethel Burying Ground I have come across a Philadelphia Inquirer article from May 31, 1889. It reports that “Robert Bryan Post 80, colored, commanded by Samuel Jones, visited Wilmot and Bethel African M.E. cemeteries. The orator was John S. Durham.”
The Honorable John S. Durham was an African American who graduated from the Institute of Colored Youths and the University of Pennsylvania. He was appointed by President Benjamin Harrison as the U.S. Diplomatic Consul to Santo Domingo and eventually as Consul-General of the U.S. to Haiti. He was the highest-ranking African American in the Harrison administration.
