It’s likely that this albaster effigy of a cross-legged knight in Pickering church is Sir William Bruce (c.1295-c.1345) who founded a chantry chapel there on the Feast of St John the Evangelist Saturday 27 December 1337.
He’s said to have fought at the Battle of Boroughbridge (or possibly at a tournament held there). His family home was at Beck Isle, Pickering, where there’s now a museum of rural life.
