He bore azure, a bend argent, cotised between six martlets or. He had 1, Adam; 2, a daughter, married John Butler; 3, Adam de la Bere of Knolston, in Gower; 4, Sir John de la Bere of Weobley Castle, in Gower, who had a moiety of Marcross manor. He married Agnes, daughter and co-heir of Sir Payne Turberville, of Coity, and had Elizabeth, married to Oliver St. John, and Margaret, married first Roger Dennis, and secondly Sir Elias Basset. The de la Bere quarterings were always used by the Lords St. John and Bolingbroke, and appear in the Basset shield over the porch at Beaupre.... ²
