m. (1) Elizabeth Cock, (2) Rebecca Chapman.

Father of Kingsmill, matric Oxon 1677.

His second son, Sir Richard Lucy 1592-1667, matriculated from Magdalen College, Oxford, in 1607, aged 15, and graduated B.A. from Exeter College in 1611. He became a student in Lincoln's Inn in 1608. Through his marriage with Elizabeth (d. 1645), daughter of Sir Henry Cock, and widow of Sir Robert Oxenbridge (d. 1616), he was life-owner of Broxbournbury, Hertfordshire. He was knighted at Whitehall, 8 Jan. 1617-18, and was created a baronet on 11 March following. He was elected M.P. for Old Sarum to the Long parliament in 1647, and sat in Cromwell's parliament of 1654 and 1656 as member for Hertfordshire. On his death (6 April 1667) Broxbournbury reverted to Sir John Monson. A portrait there is said to represent Sir Richard (cf. Notes and Queries, 2nd ser. vii. 87). Sir Richard's son Kingsmill, F.R.S. (d. 1678), of Facombe, Hampshire, who was created D.C.L. at Oxford at the installation of the Duke of Ormonde as chancellor in 1677 (Wood, Fasti, ed. Bliss, ii. 364), was the second baronet, and married Theophila, second daughter of George, earl of Berkeley, who subsequently became the wife of Robert Nelson [q.v.]. With the death of Sir Kingsmill's son, Berkeley, also F.R.S., on 19 Nov. 1759, aged 87, the title became extinct.
