Ralph’s place in the pedigree of the Astleys, an old Warwickshire family, is uncertain. His will shows that he was a lawyer with roots at Hillmorton, but he did not hold any manorial property there and most of his estate was situated in south-east England.
In spite of his purchase of lands from Peyto and family links with Warwickshire, Astley did not serve the Crown as an office-holder in that county. It was for Hertfordshire that he was appointed an ad hoc commissioner, j.p. and sheriff, and by the later 1430s he was sufficiently established there to gain election to the Commons as one of its knights of the shire. He was made a j.p. for his adopted county a day after the dissolution of the Parliament of 1437, but was no longer on the bench when pricked as sheriff of Essex and Hertfordshire in November 1441. During his term as sheriff several prisoners broke out of Hertford gaol, although the King afterwards pardoned him for these escapes,
Astley served his term as sheriff late in his career, for he died on 28 Feb. 1446.
Astley was succeeded by his son Philip.
