As the youngest of six brothers, Lucy inherited only a £30 annuity and pursued a career in the law. His shortlived clerkship on the Midland circuit, which commenced before he completed his legal training, was presumably arranged by his eldest brother, Sir Thomas, a leading Warwickshire gentleman, who was certainly responsible for Lucy’s repeated election to Parliament for Warwick.
Lucy’s later career was closely tied to that of his brother Sir Richard, a resident of Broxbourne, Hertfordshire, who probably facilitated his marriage into a family from neighbouring Hoddesdon. Sir Richard stood to inherit extensive Hampshire estates from his mother, and Lucy was a trustee of the 1630 deed which confirmed this arrangement. During the early 1630s Lucy lived in Cripplegate, perhaps in his mother’s townhouse, but by 1637 he had settled in Westminster, where he occupied a dwelling in the Strand.
Although not conspicuously wealthy, Lucy married his daughters advantageously to Sir Edward Atkyns†, later chief baron of the Exchequer, Sir Philip Meadowes, ambassador to Denmark, and Sir Samuel Eyre, a King’s Bench justice. He retained his ties with Lincoln’s Inn as late as 1681, and was still living in Westminster the following year. However, by 1686 he was resident at Hammersmith, where he was buried on 4 Feb. 1687. In his will, drawn up on 7 Sept. 1682, he bequeathed £100 each to his sons-in-law and two surviving daughters, and made generous provision for his servants. Lucy left no heirs in the male line, but two of his grandsons, Robert Eyre and Sir Philip Meadowes, entered the Commons in the 1690s.
