In a publication entitled The House of Commons 1715-1754, there is an entry for William Gwyn Vaughan as follows:

“VAUGHAN, William Gwyn (?1681-1753), of Trebarried, Brec.
Breconshire 30 Aug. 1721-1734
b. ?1681, 2nd s. of Gwyn Vaughan of Trebarried by Mary, da. of William Lucy, bp. of St. Davids 1660-77. educ. Queen’s, Oxf. 12 May 1698, aged 16. m. Frances da. and h. of John Vaughan of Hergest, 6s. 2da. suc. bro. Thomas 1694.

Vaughan was returned as a Tory in 1721, when his name was sent to the Pretender as a probable supporter in the event of a rising. A list of payments totalling £2,000 to Members of Parliament, apparently prepared by Sunderland for George I about this time, contains the item: ‘a M. Vaughan, beaufrere de M. Morgan de Tredegar, £200’. He spoke against the Government on the Hessians in 1730, and on the army estimates, 15 Feb. 1733, voting against the excise bill that year and for the repeal of the Septennial Act in 1734. Defeated in 1734 by an opposition Whig, he did not stand again. He died 31 Aug. 1753.”

Does anyone know if there is a pedigree for this family that would connect it to the “Vaughans of Jordanston”, whose lineage was set out in the Pembrokeshire Historian article entitled “Jordanston in Dewisland”?
