The account of the descendants of Sir David Williams given by Theophilus Jones (op. cit., iii, 82-3), Burke (Extinct Baronetcies, 568), and Jane Williams in her article on Glasbury (Arch. Camb., 1870, 308-9) is misleading — e.g. two generations have been mixed up, as is proved by R. W. Banks (Arch. Camb., 1879, 308-9, or Theophilus Jones, 3rd ed., iii, 91-2). Sir David was succeeded by his son Sir HENRY WILLIAMS, who d. 1636. It was probably he (and not his son of the same name, as given in the list of Members of Parliament at the end of Hist. Brecknock) who was the member for the borough of Brecon 1601-4; he was knighted in 1603 and became a member of the Council of the Marches in 1617; again, it was probably he who was member for the county of Brecknock from 1620 to 1628. On the other hand, as the Member of Parliament for that county in 1628-9 is referred to as ‘Henry Williams Esq.’, it seems likely that this was the son — Sir HENRY WILLIAMS (d. 1652), who was created a baronet in 1644, and who welcomed Charles I to Gwernyfed when the latter visited Wales after the battle of Naseby (1645). As none of his male descendants merit attention here, it is unnecessary to trace the lineage further; Burke claims that the baronetcy continued until 1798, but Banks quotes contemporary evidence to show that it had lapsed before 1727, and this is far more credible, for two brothers died without male issue, leaving their sister, ELIZABETH WILLIAMS, as sole heiress. With her marriage Gwernyfed passed to a new line of Williamses.
