Luttrell, Simon (1643–98), Jacobite soldier and governor of Dublin, was eldest among four sons of Thomas Luttrell of Luttrellstown, Co. Dublin, and his wife Barbara, daughter of William Sedgrave; he was elder brother of Henry Luttrell (qv), with whom he spent some time at the French court. On his return to Ireland (1672) he married Catherine, daughter of Sir Thomas Newcomen, baronet, and succeeded to his father's estate at his death (1674). Appointed lord lieutenant of Co. Dublin and a privy councillor by the lord deputy, the earl of Tyrconnell (qv) in 1687, he represented Co. Dublin in the 1689 Jacobite parliament and was military governor of the city of Dublin. A staunch adherent of the Stuarts, he raised a regiment of 374 dragoons, prepared Dublin's defences against an awaited assault, and disarmed its protestant inhabitants. He set out for Dundalk on the landing of the duke of Schomberg (qv). He was one of the Irish delegation which went to Saint-Germain after the lifting of the first siege of Limerick to call for the removal of Tyrconnell from the viceroyalty. Along with Peter Creagh (qv), catholic bishop of Cork, he prevented his brother Henry and Col. Nicholas Purcell (qv) from throwing overboard Major-General Thomas Maxwell, whom they believed hostile to their embassy, which was in any event unsuccessful.
Luttrell remained in France, not returning to Ireland until autumn 1691 when he was on board the French fleet that arrived in Limerick on 28 October, three weeks after the conclusion of the treaty. He refused to avail himself of the civil articles of Limerick and returned to France, where he was given command of an infantry battalion of the newly constituted Jacobite army in France; he served with distinction under Marshal Catinat in Italy, and also commanded an infantry battalion of 1,000 men for the abortive invasion of England (1692). He was later transferred to the service of the duc de Vendôme in Catalonia. He died, aged 55, on 28 October 1698 at Crest, a small town located midway between Valence and Montélimar, south-west France. A memorial inscription on a slate of black marble near the holy-water font in the Irish College in Paris dates his death at 6 September 1698.
Simon Luttrell appears to have suffered from bad health. Writing to the 2nd duke of Ormond (qv) in late 1688 he complained that he had been ill for ten years and was threatened with paralysis (Kingston, 89). The duke of Berwick (qv), who was well acquainted with the Luttrells, considered Simon to be ‘of a mild disposition and always appeared to him to be an honest man’ (O'Callaghan, 98).
