Morgan was the first of his family to use a settled surname rather than the patronymic style. His father claimed ancestry from the kings of Brecon but was not particularly prominent in Breconshire, and Morgan therefore pursued a legal career rather than settle for a relatively modest inheritance. In 1616 he entered the Middle Temple, soon obtaining a chamber there and establishing an association with Walter Pye I*, which was to prove the most important of his professional life. Pye requested Morgan to stand surety for several new admissions, including the sons of Breconshire gentlemen, Herbert Price† of the Priory and Sir Henry Williams* of Gwernyfed (Morgan shared his chamber with the new arrival).
Morgan’s wealth allowed him to secure a profitable marriage with the youngest daughter of Sir William Morgan* of Tredegar, one of the most powerful gentlemen in Monmouthshire society.
During the 1620s one Sybil Wayte of London tried to prove in the Court of Arches that Morgan had married her in 1624 and that he had also produced a number of children by her, including a son. Morgan later acknowledged that Sybil was his ‘wench’, that they lived in the same house, had an illegitimate daughter and that he supplied her with money, but the case did not proceed to sentence and Morgan, with the backing of Pye, used his ‘eminence’ to silence her.
In 1648 Sybil Wayte revived the charges against Morgan, encouraged to do so, according to Morgan himself, by ‘the soldiery who have made her more bold and impudent than a preacher to a company of foot’. However, at his death in May 1649, Morgan left nothing to Sybil or his children by her, and though Sybil claimed one-third of the estate as her dower and prosecuted Morgan’s executors in a Chancery suit which dragged on until 1654, a decree was eventually issued on behalf of Morgan’s heir.
In his will of 27 May 1649, Morgan directed that he be buried in Brecon church next to his father. He left his estates to his son, William, and provided for a portion of up to £2,000 for his daughter, Blanche. Morgan entreated his children to be guided by his brother-in-law, Thomas Morgan† of Machen and, mindful of his legal difficulties and earlier indiscretions, advised them that ‘generally the choice of youth in the way of marriage is heady and foreruns hasty, and late repentance which followeth at the heels’.
