Details of this MP’s origins are sparse, although it seems most likely, in view of his parliamentary career, that he was a member of the Sussex family of this name which had owned the tiny manor of Rowses near East Grinstead.
Like other Chancery clerks Rous was made party to a number of business transactions during his career so that these, notably gifts of goods and chattels, might be recorded on the dorse of the close rolls. They included a gift made by a London grocer to Adam Moleyns, keeper of the privy seal, in April 1445.
Rous’s return as an MP to the two Parliaments held in 1449 undoubtedly owed much to his prominence as a royal servant, although his election for two boroughs controlled by the duke of Norfolk, John Mowbray, suggests an otherwise undocumented tie with that magnate.
