Heir to a family with estates in Glamorgan and Monmouthshire, Lewis Morgan attended the predominantly Welsh populated Jesus College, Oxford before moving to the Middle Temple. In May 1626 he was granted a passport and travelled to the Netherlands, where he attended Leiden University.
Morgan was returned at the 1628 general election for Cardiff, where his family possessed a grand town house, and his father’s employer, the 3rd earl of Pembroke, was lord of the manor.
Shortly after the dissolution Morgan was knighted and journeyed to the Netherlands with the Welsh soldier Charles Price* of Pilleth.
Morgan predeceased his father, and was buried at Hampstead, Middlesex on 3 July 1635. Administration of his estate was granted to a creditor, William Carne, a kinsman of his paternal grandmother.
