Sir William Williams, 6th Baronet (– 23 December 1696) of Faenol (Vaynol) was a Welsh politician and landowner elected as MP for Caernarvonshire from 1689 until his death.
Williams was born in around 1663, the son of Sir Griffith Williams (d.), 4th Baronet, of Faenol (Vaynol), and his wife Penelope, daughter of Thomas, 1st Viscount Bulkeley. Sir Griffith was one of the Williams baronets,[1] and was succeeded by his son Sir Thomas Williams (d.) as 5th Baronet. Sir William succeeded his brother in around 1673.[2]
In 1688, he succeeded Robert, 2nd Viscount Bulkeley as Vice-Admiral of North Wales and, in the following year, he was elected as MP for Caernarvonshire.[3] He married his cousin Ellen Bulkeley, the daughter of Robert, 2nd Viscount Bulkeley.
Williams died on 23 December 1696 and the Baronetcy became extinct. Ignoring the claims of an impostor, Arthur Owen, who claimed to be a relative, Williams left his Vaynol estate to the descendants of his friend, the late Sir Bourchier Wrey, 4th Baronet.[4]
