Hi Roy,
Link didn’t work - here it is.
Without sourcing or citation for the narrative:
https://www.findagrave.com/memorial/176878586/john-bunch
John Bunch I was the son of John Punch an African slave brought to York County, Virginia from either Cameroon or the Ivory coast. John Bunch's mother (John Punch's wife) was an unnamed white woman. He had three sons, John II, Henry and Paul. The wife of John Bunch I is unknown, but he was NOT THE HUSBAND OF MARY BARNARD.
If you compare that with the geni tree (very well cited if I may so myself) FindAGrave seems off a generation.
