After unsuccessfully contesting Chester as a Whig in 1722, Williams was returned in 1725 for Anglesey by the Bulkeleys, the leading Tory family in the county, probably on the recommendation of his first cousin, Watkin Williams Wynn, who considered him ‘the only person at present in Lord Bulkeley’s interest that can in all likelihood meet with success’.
He died 14 Jan. 1742.
