Everard, Sir Redmond (1689–1742), 4th baronet, MP, and later Jacobite, was born in Co. Tipperary, probably in Fethard, elder of two sons of Sir John Everard, baronet, of Fethard, and his wife Eleanor, eldest daughter of Pierce Butler, 6th Lord Caher, and Elizabeth Mathew. Sir John Everard was MP for Fethard in King James's (qv) parliament of 1689 and a captain in Col. Nicholas Purcell's regiment of horse in the Jacobite army. He was killed at the battle of Aughrim (12 July 1691). Lady Everard died soon afterwards, leaving young Sir Redmond as an orphan to the care of his guardian Mary Butler, duchess of Devonshire. By her he was brought up as a protestant. Thanks to the influence of the duke and duchess of Devonshire the lands forfeited by Sir John Everard in 1691, with a total acreage of 5,903, were restored to Sir Redmond by a private act of the English parliament in 1702.
On 30 June 1707 Sir Redmond was elected sovereign of Fethard and he was sworn on 29 September 1707, taking the oaths of allegiance and supremacy. From 25 July 1711 to 1713 he was an MP for the city of Kilkenny. He was elected at the by-election caused by the death of William Henry Zuylestein. For the parliament of 1713–14 he was elected (26 October 1713) as representative for Fethard. He was considered to be a tory. He received the degree of doctor of civil law from Oxford University on 22 September 1715.
After Queen Anne's death (1714) Sir Redmond became a supporter of James Stuart, the Old Pretender, who lived as King James III in exile in France. From 1716 onwards he played an active part in the Jacobite cause, closely cooperating with the duke of Ormond (qv), Dr Francis Atterbury, bishop of Rochester, and other Jacobite leaders. In these circles he was known as ‘the little knight’. In 1719 he was involved in Cardinal Alberoni's project for a Spanish expedition to Scotland in support of the Stuarts, and also in negotiations with Sweden to procure Swedish support. During this period he lived in the parish of St James, Westminster. After 1721, the year Sir Redmond married, he and his wife lived in exile in France and settled in the vicinity of Paris. In 1724 they lived at Marley near Saint-Germain-en-Laye and later at Chatou, near Nanterre. In 1738 they moved to Carrière near Poissy sur la Seine, and finally to Mignot. On 20 June 1723 Sir Redmond Everard was created Viscount Everard by James III.
During most of his life Sir Redmond had financial problems, mainly caused by two reasons: first, his inability as an absentee landlord to manage his estate in Ireland properly, and secondly, his financial support to the Jacobite cause. His growing debts resulted in a number of mortgages on his Irish property, and several court cases with creditors dragged on for many years. In Sir Redmond's marriage settlement of 1721 it was agreed that his estate in the barony of Middlethird was to be vested in trustees for the benefit of the family. The estate near Clogheen, in the barony of Iffa and Offa, however, was to be conveyed in trust to be sold to the satisfaction of some of Sir Redmond's debts, to the amount of £22,161. 10s. His wife's dowry of £10,000 was another source for debt-redemption. More property had to be sold, as besides the debts mentioned in the marriage settlement there were more debts to the amount of £6,912. With the consent of parliament, enacted in 1727, several lands near Fethard and a number of houses in Clonmel were sold. As a result of these sales, Sir Redmond's estate was considerably reduced in extent. That was, however, not the end of his financial troubles. Mismanagement of his Irish estate caused new problems. While residing at Mignot near Paris, Sir Redmond had to live entirely on credit for several years and was obliged to apply to a Paris banker, named Quane, who later sold his claim to Alderman Richard Dawson (d. 1766) of Dublin for £11,000.
Everard married (15 June 1721), at Westminster abbey, Mary Drake (15 June 1694–15 August 1742), only daughter of Montague Drake of Shardeloes, Bucks., and Jane, daughter and heiress of Sir John Garrard, baronet. Sir Redmond made his will on 18 March 1739. He died 13 April 1742, and his wife Mary died four months later. They left no issue, and in consequence the baronetcy became extinct. The property was inherited by James Long (who took the name ‘Everard’ as a condition of the will), second son of John Long of Killoran, Co. Tipperary, and his wife Mary, daughter of Theobald Butler, 7th Lord Caher, and Mary Everard, sister to Sir Redmond's father. A painting of Sir Redmond (school of Sir Godfrey Kneller) was for a long time in the possession of the Everard family of Randlestown, Co. Meath. The present whereabouts of this portrait is unknown.
