Sir John Edwards, 1st Baronet, of Garth

Sir John Edwards, 1st Baronet (15 January 1770 – 15 April 1850), was a Whig politician who served as Member of Parliament for Montgomery from 8 April 1833 to 23 June 1841. The Edwards Baronetcy, of Garth in the County of Montgomery, was created for him in the Baronetage of the United Kingdom on 23 July 1838.

Early life Edwards was the son of John Edwards (d. 1789), a solicitor of Plas Machynlleth (also known as 'Greenfields'), Montgomeryshire, and his third wife, Cornelia ( Owen) Edwards. His father acquired the Garth estate, including the profitable Van lead mines, by his marriage to John's mother, the only child and heiress of Richard Owen.

Sir John added to the mansion, and expanded the Garth estate by purchase of parts of the Peniarth Estate along the Dyfi Valley. From her first marriage to John Owen Herbert of Dolforgan Hall, she was the mother of Harriet Avarina Brunetta Herbert, who married Walter Long (eldest son of Walter Long). Harriet's brother was John Willes-Johnson, an officer in the Royal Navy who served as MP for Montgomery. Together, they were the parents of:

Mary Cornelia Edwards (1826–1906), who married George Vane-Tempest, Viscount Seaham, later to become Earl Vane and the 5th Marquess of Londonderry, in 1846.
