...The ashes of Sir Richard and his wife Margaret, daughter of Sir Thomas ap Griffith, knt., repose beneath an alabaster monument in the Herbert chapel, adjoining St. Mary's Church at Abergavenny. Their figures are recumbent with uplifted hands; his in a suit of mail, the head bare, and supported by a sheaf of arrows (his crest), the feet resting on a lion; hers habited in a long robe. Upon the death of Sir Richard, Colebrook came to his eldest son, Sir William Herbert, and continued in his descendants, the ninth of whom, Sir James Herbert, dying in 1709, without male issue, it was conveyed by that gentleman's daughter, Judith Herbert, to her husband, Sir Thomas Powell, knt. Beside his eldest son, Sir William, Sir Richard, of Colebrook, left two other sons, namely, Sir Richard Herbert of Montgomery, grandfather of the celebrated Edward, Lord Herbert of Cherbury, and Thomas Herbert, ancestor of the Herberts of Tintern and York. ²
