Robert Knollys, son of Sir Francis and Catherine was born in 1550, the sunday sennett after all halou daye, which would have been 8 Nov. 
At the age of about 20 he accompanied William Drury, Vice Marshall of Berwick on raids into Scotland against the infamous border reivers. Two years later he was elected the Member of Parliament for Reading in Berkshire and Breconshire in Wales. Between 5 Feb 1578 and 1582 he held the position of Usher of the Tower Mint  and then in 1587 he was appointed a Gentleman of the Privy Chamber, a position with the potential for great influence in Court matters.  He was affectionately known by his cousin Queen Elizabeth as Robin and although he was part of the entourage of his nephew Robert Devereux he avoided implication in the 1601 rebellion. 
In about 1585 Robert married Catherine Vaughan, daughter and heiress of Rowland Vaughan of Porthaml, Breconshire.  This marriage brought him valuable lands in Wales, although he had to fight several legal battles with Vaughan connections to hold them.  They had two daughters: Frances (sometimes erroneously called Catherine) who married Sir Charles Vaughan at St Margaret, Westminster on 6 Nov 1605 and Lettice who married Framlingham Gawdy MP.
