"Mr. G. T. Clark, F.S.A., of Dowlais, a well-known antiquary, in his contributions towards a cartulary of Margam, states that no authentic pedigree of the Welsh de la Beres has been preserved. They seem, he says, to be of Gower. 1. Sir John de la Bere, who was father of David and Isabel. 2. Sir David de la Bere, 25th Ed. I (1297), 7th Ed. II (1314), and 1.7th Ed. II (1324). 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.... 1
