In the churchyard of St John the Baptist Church, Bishop’s Castle, is an unnamed grave, dedicated to 'I.D., a Native of Africa', who died in 1801. Nothing is known for sure about the individual remembered by this gravestone, but the inscription is one used frequently by abolitionist sympathisers: 'God hath made of one blood all nations of men'. With connections to English Heritage’s ‘Sites of Memory’ project, in 2007 researchers attempted to find out more about the occupant of the grave. Partners in the project included Bishop's Castle Heritage Resource Centre, the parish Church of St John the Baptist and the Community College in Bishop's Castle. The research leaflet was revised and reprinted in 2015, as new evidence came to light about a local family, the Oakeleys, who had an interest in a plantation in Jamaica. Bishop's Castle Heritage Research Centre volunteers continue their research into the identity of ‘ID’ and the reasons they came to Bishop's Castle.
