Conway spent most of his early life in the Netherlands, where his father, Sir Edward, was lieutenant-governor of the Cautionary Town of Brill. He secured his first military command there while still officially a minor, and in 1614 served under his uncle, Sir Horace Vere, during the Jülich-Cleves crisis. In the following year he obtained a pass to visit France, but may not have used it. When Brill was returned to the Dutch government in 1616 he obtained a commission in a new regiment formed from the Brill garrison, and remained in the Low Countries for another seven years, paying only occasional visits to England.
Conway was now a veteran of numerous campaigns and sieges, but he had also fallen heavily into debt. In October 1623 he resolved to return home again to order his affairs, but could not guarantee that he would not be arrested by his creditors. A solution presented itself when Parliament was summoned in December, as membership of the Commons would provide him with precisely the protection he required. On 10 Jan. 1624 his father wrote: ‘I have sought to get you a burgess’s place of the Parliament, and am confident I shall have one for you. So soon as the election is made I will send an express for you.’
With some difficulty, Conway’s father secured him a promotion as second-in-command in Lord Willoughby’s regiment, and by September he was back in the Low Countries with his brother Thomas as one of his junior officers. The campaign was beset by problems, but Conway’s own prospects were rising. His father, ennobled in March 1625, was one of the duke of Buckingham’s closest allies, and in the following month he informed Conway that he should expect a warrant, as ‘the duke reckons you in the number of his’.
At the 1626 general election Lord Conway again tried to secure his son a seat at Warwick, but left his nomination request too late, and instead used his influence as captain of the Isle of Wight to have him returned at Yarmouth. Despite Buckingham’s impeachment, Conway made no recorded contribution to the Parliament’s proceedings.
In 1629 Conway obtained the governorship of County Londonderry, and settled at Lisburn, where he formed an extensive library. He inherited his father’s titles two years later, but leased his family seat at Ragley to the 2nd Lord Brooke (Robert Greville*). After the Crown took direct control of the Londonderry plantation in 1635, he returned to England, and spent the next three summers serving as a volunteer in naval patrols in the English Channel and North Sea.
