Sir Hugh Williams, 8th Baronet (1718 – 19 August 1794), was a British Army officer and landowner in Wales, who sat in the House of Commons between 1768 and 1794.
Promoted Captain in the 34th Foot in 1744, he succeeded to the baronetcy on the death of his cousin Sir Robert Williams, 7th Baronet, in November 1745.
[4] Correspondence indicates that Sir Hugh was becoming involved in politics in Beaumaris, partly in the interest of his stepson Thomas Bulkeley, but was hindered by the secrecy of his marriage (due to his father-in-law's disapproval of Williams).
As this was refused Sir Hugh retired from the Army on half-pay in December 1764 to take care of affairs at Beaumaris.
She was the only daughter and heiress of Thomas Rowlands of Caerau, Anglesey, but as her father disapproved of Williams, the marriage was kept secret.
