John Morgan

John Morgan had two sons by his wife, Martha Vaughan (pictured).

John Morgan (4 January 1671 – 7 March 1720) was a Welsh politician who sat in the House of Commons from 1701 to 1720.

Morgan was the youngest son of William Morgan and his wife (and cousin) Blanche. When his elder brother Sir Thomas Morgan died without surviving children in 1700, he inherited the family's Tredegar Estate, the two middle brothers having predeceased him.

Morgan, a prominent Whig, entered the House of Commons as Member of Parliament for Monmouthshire in 1701, replacing his brother, and represented it until his death in 1720. He was created custos rotulorum of the county the same year, in succession to his brother.

In 1715, Morgan inherited Rhiwperra Castle and the manor of Gwynllwg from his uncle, John Morgan and obtained the lord lieutenancy of the county and also of Brecknockshire. He died in 1720, and was buried on 19 March 1720 at Machen.
