Young came from a cadet branch of a Welsh family which had assumed an English surname after marrying a local heiress seven generations back. After studying at Lincoln’s Inn he found employment as secretary to Lord Zouche, who became lord president of the Marches in June 1602. Zouche used the enfranchisement of Bewdley in 1605 to provide Young with a seat at Westminster and himself with a spokesman in the Commons.
Following his master’s loss of office in 1607, Young remained in Zouche’s employment but he was in no position to stand for election to the Addled Parliament. In June 1615, however, Zouche became lord warden of the Cinque Ports, and doubtless it was through Zouche’s intercession that Young was subsequently appointed collector of customs at Sandwich. Young remained in Zouche’s service until at least March 1616, when the corporation of Dover presented him with a silver cup ‘in respect of the love and affection that Mr. Young, his lordship’s secretary, hath and may have to this corporation’.
A couple of weeks after he was knighted, Young married the widow of a wealthy London Draper, Sir Thomas Hayes, for whom he had acted in a property transaction a few years earlier.
Young played a modest, though not insignificant, role in the 1621 Parliament. His appointments, of which there were six, included the committee for privileges and returns (5 Feb.), and the conference of 16 Feb. with the Lords on recusancy.
Young’s evidence played a crucial part in bringing about the fall of the lord chancellor, and threatened to bring an end to his own career in royal administration, but the ‘credit and favour’ of Pye’s patron Buckingham and ‘the intercession of my friends’ ensured that he was no loser by his betrayal, and he was made a member of the privy chamber.
During the course of 1623 Young provided Lord Zouche with a steady stream of news from Court, and one occasion he even described himself as Zouche’s ‘faithful servant’. Following the announcement of fresh parliamentary elections in 1624, Zouche again obtained a parliamentary seat at Dover for his former secretary, though not before Young had to take out his freedom for a second time, ‘having lost the same, by being absent two years’.
In the spring of 1624 Young became a tenant of Lord Zouche’s house at Odiham, in north-east Hampshire.
Following the abolition of Star Chamber in 1641 Mynne, claiming that he had been deprived by an illegal court, appealed to the House of Lords for restoration to office.
