Rodney was born at Pilton and ‘bred together in the schools of Trowbridge and Oxford’ with his Seymour kinsmen. He went on to the Middle Temple, but by his own account ‘saluted only the law afar off, and misspent his time’.
In December 1620 Rodney was admitted to the freedom of Wells, five miles from Stoke, without charge because his late father ‘was a great friend of the city’; and on the same day he was also elected to represent the town in the third Jacobean Parliament. He was appointed to two committees, one to confer with the Lords over the recusancy petition on 16 Feb. 1621, and the other to consider a bill to settle the lands of a recusant on Lord Holdernesse (13 March).
Re-elected for Wells to the next three parliaments, Rodney left no mark of his presence in 1624. In the first Caroline Parliament he was named to the fast conference of 23 June, and appointed to consider a bill to prevent tipping in inns and alehouses (24 June).
Despite Poulett’s fear that this speech had earned ‘envy, reproaches, and the raking of ill tongues’, Rodney was returned for the county in 1628.
A week later Rodney supported John Baber*, the recorder of Wells, against particular charges brought by Phelips, that soldiers had been unlawfully billeted in the town. Rodney admitted that he and Robert Hopton* had ‘advised’ Baber to find lodgings for the troops, but claimed that none had been ‘forced to receive a soldier that had not a mind to it’.
Rodney remained active in county administration, and was returned for Wells at both elections in 1640. In July 1642 he joined his friend and kinsman William Seymour, now 2nd earl of Hertford, with the royalist forces there.
