Rous’s ancestors owned property in south Devon as early as the thirteenth century. His father, a younger son, settled in Sussex, where Rous grew up in a markedly puritan atmosphere. His prospects were transformed in 1572 when his childless uncle designated him as his heir, and five years later he inherited a very substantial estate in Devon and Cornwall, including the seat of Halton. In this ‘pleasant and commodious dwelling’ overlooking the Tamar, Rous delighted in ‘a kind and uninterrupted entertainment’ of his friends, who included Sir Francis Drake† and the antiquary Richard Carew†. Possessed of almost 10,000 acres by the end of his life, he was one of Cornwall’s richest residents, with a subsidy rating in 1604 of £35.
Rous’s newly acquired prominence and general local standing suffice to explain his election as a knight of the shire in 1604. He was appointed on 26 Mar. to attend the conference on wardship, purveyance and other grievances, and two days later to accompany the Speaker to the king with the Commons’ explanation of their proceedings over the Buckinghamshire election. Nominated on 24 Mar. to the select committee to consider the continuance or repeal of statutes, he was also named to help scrutinize the bishop of Bristol’s published riposte to the Commons’ objections to the Union, and prepare for a conference about it (1 June).
Rous’s godly fervour was much to the fore in the 1605-6 session. He was named on 3 Feb. to attend the conference on recusancy laws, and of his four bill committee appointments two had religious themes, the public commemoration of the Gunpowder Plot, and Sabbath observance (21 and 29 January). Predictably he was nominated to the committee for the new bill concerning the estates of the Suffolk Rouses (1 Feb.), and doubtless also followed the progress of the bill for sale of lands belonging to his late colleague Sir Jonathan Trelawny*, since he was named in it as a trustee. On 23 Mar. he was again given leave to depart ‘for very special occasions of his own private [affairs] and of the king’s service’, and on his return to Cornwall he brought his friend Richard Carew a message from Camden.
The Trelawny estates Act proved defective, and a new bill involving the same trustees was passed during the 1606-7 session. Rous was nominated on 24 Nov. to attend a conference about the Union. The subjects of his six legislative committee appointments included free trade, ecclesiastical courts, and non-resident clergy (26 and 29 Nov., 4 March).
As vice-warden of the Stannaries, according to Fitz-Geffrey, Rous ‘often desired to have some divine a spectator and arbitrator of his proceedings ... to be present at the scanning and censuring of cases, desiring to decide all matters by the best rule of religion and conscience’. He apparently remained active well into old age, marrying for the third time only months before his death, which was reportedly hastened by a chill caught while attending a sermon.
