Rous belonged to a junior branch of the Cornish family which supplied four Members during this period. Like his uncle, Sir Anthony Rous*, he grew up in Sussex, where his father was a minor landowner. However, as the younger son of a younger son, he could not expect a substantial inheritance, and therefore sought his fortune in London. He may have been the man of this name who was a page to the earl of Essex at the time of the abortive 1601 rebellion.
In 1622 Rous contributed £13 6s. 8d. to the Benevolence for the recovery of the Palatinate, and began to participate in Surrey’s local government. However, he earned a summons before the Privy Council four years later by defaulting in the county’s musters.
The profits of office enabled Rous in 1630 to purchase Polesden manor, close to his home at Fetcham. He made his will on 1 May 1629, providing portions totalling £700 for his two daughters, and died in January 1632. He was buried in Fetcham church, where a marble epitaph was erected in his memory.
