Sir Thomas Lucas (died 1649) of Lexden, Essex, England, along with his younger brothers, Sir John Lucas (d.1671) (in 1645 created Baron Lucas), and Sir Charles Lucas (d.1648), distinguished himself as an officer fighting for the royalist cause in the Civil War.[1][2]


Lucas was the eldest son of Sir Thomas Lucas (d. 1625) of St John's, Colchester, Essex, by his mistress and future wife Elizabeth Leighton, daughter of John Leighton of London, gentleman. He was illegitimate as he was born before his father's marriage with Elizabeth Leighton.[3] His brothers Sir John Lucas (d.1671) (in 1645 created Baron Lucas) and Sir Charles Lucas also fought for the King. His younger sister Margaret Lucas, a prolific writer and a scientist, was the wife of the Duke of Newcastle.[4]


His father purchased for him the manor of Lexden, Essex, from the heirs of Robert Ratcliffe, Earl of Sussex [5]

Lucas obtained the command of an English troop in the Dutch service, and was knighted by Charles I on 14 April 1628.[6] In December 1638 Thomas Wentworth, 1st Earl of Strafford gave him the command of a troop in the Irish army.[7] He was one of the officers in whom Ormonde most confided during the Irish Rebellion of 1641, and held the rank of commissary-general of the horse. He distinguished himself at the Battle of Kilrush (15 April 1642), and was badly wounded at the Battle of New Ross on 18 March 1643.[8]

From 1642 Lucas was a member of the Irish Privy Council, took part in negotiating the cessation of hostilities in 1643 and the treaty of 1646, and was consequently held a delinquent by parliament.[9] He was, however, allowed to compound for his estate on paying a fine of £637 in 1648, and died before October 1649.[10]


Lucas married Mary Byron, daughter of Sir John Byron of Newstead, Nottinghamshire.[11]
