Vernon should not be confused with two namesakes who served as Household officials: one, appointed cofferer in 1610, angered his colleagues on the Board of Greencloth by selling his office to (Sir) Arthur Ingram*, while the other served as avener of the Stables and was knighted in 1615.
Although he did not sit in the 1604 Parliament, Vernon and his relative Henry Vernon of Stokesay sponsored a private bill challenging Sir William Herbert’s* claim to the lordship of Powis, a vast estate in northern Montgomeryshire. In 1587 Herbert’s father had purchased the lordship from the illegitimate son of the last Lord Grey of Powis, whose title was hotly disputed by Henry Vernon, who claimed descent from a daughter of the 1st Lord Grey. Herbert’s brother, the 2nd earl of Pembroke, helped him to make good his title, and so the 1604 bill was effectively a final bid to establish the Vernon claim, which Sir Robert stood to inherit along with what little remained of the Stokesay estate after the death of his childless uncle.
Vernon’s ancestry and estates placed him among the first rank of Shropshire families, and his status was confirmed by his marriage to a sister of Sir Robert Needham*. His election as knight of the shire in December 1620 was probably arranged by Needham, who was named second on the return, and seems to have been uncontested, as (Sir) Richard Newport, who had taken the junior county seat in 1614, signed the indenture and found a burgess’s place at Shrewsbury.

Following a concerted effort by several Shropshire MPs, the bill was sent back to committee for addition of the required proviso.
The Shropshire county seats were customarily assigned on a rotation, and Vernon was not re-elected in 1624. The return for that year is lost, and that for 1625 damaged, but there is no indication that Vernon contested either, and in 1626 he signed the indenture returning Rowland Cotton and Richard Leveson. In January 1623 he was one of the Shropshire j.p.s who endorsed the Shrewsbury Drapers’ ongoing case against the Welsh clothiers, and in 1627 he was involved in the raising of recruits for the expedition to Ré.
