Marie Stewart (7 April 1576 – 11 May 1644) was a Scottish courtier and Countess of Mar by marriage. She was the daughter of Esmé Stewart, 1st Duke of Lennox and Catherine de Balsac d’Entragues (d. c.1631) and a favourite of James VI of Scotland. After her marriage to John Erskine, 2nd Earl of Mar, as was customary in Scotland, she did not change her name, and signed her letters as "Marie Stewart".Claire M. Elder, "Stewart [Stuart], Marie, countess of Mar", Oxford Dictionary of National Biography, 8 August 2024. E. Dunbar Dunbar, Documents Relating to the Province of Moray (Edinburgh: David Douglas, 1895), p. 54.

Marriage and conversion In February 1584 James VI proposed that Marie Stewart might marry Lord Home or John Home of Coldenknowes. She was said to be "little above seven years old".William Boyd, Calendar State Papers Scotland, vol. 7 (Edinburgh, 1913), p. 27 no. 26.

Marie and her older sister Henrietta came to Scotland in 1588, arriving at Leith while James VI was at the siege of Lochmaben Castle.John McGavin, "Spectatorship in Scotland", Janet Hadley Williams & J. Derrick McClure, Fresche Fontanis (Cambridge Scholars, 2013), p. 289 citing NRS GD 75/563. Their older brother Ludovic had been summoned to Scotland in November 1583.

Her second sister, Gabrielle was a nun in France at Glatigny, and a scheme for her to marry Hugh Montgomerie, 5th Earl of Eglinton in 1598 came to nothing.David M. Bergeron, The Duke of Lennox, 1574-1624: A Jacobean Courtier's Life (Edinburgh, 2022), p. 28: Scots Peerage vol. 5 (1908), p. 356: William Fraser, Memorials of the Montgomeries Earls of Eglinton, vol 2 (Edinburgh, 1859), no. 201, now NRS GD3/2/15/10.

Marie became a lady-in-waiting in the household of Anne of Denmark, queen consort of James VI, in December 1590 at Henrietta's request.Calendar State Papers Scotland, vol. 10 (Edinburgh, 1936), p. 429.

It was thought that Marie might marry the Earl of Argyll instead of a suggested bride, Agnes Douglas, a daughter of the Earl of Morton by the persuasion of "very great personages".Calendar State Papers Scotland, vol. 10 (Edinburgh, 1936), p. 687. This match had been discussed in March 1589 by an English man at the Scottish court, Thomas Fowler, who noted that Marie Stewart and her sister were Catholics.Calendar State Papers Scotland, vol. 10 (Edinburgh, 1936), p. 17 citing British Library Cotton Caligula D.

He was older at thirty five, she was regarded as "ane tender bairn".Michael Pearce, "Maskerye Claythis for James VI and Anna of Denmark", Medieval English Theatre, 43 (Cambridge: Brewer, 2022), p. 121. A story descended in the family of the Earls of Haddington and was recorded by Sir Walter Scott that at first Marie scorned the older man, and James VI hearing of this, encouraged his old friend, swearing an oath, "ye shanna die, Jock for onny lass in a' the land", meaning in modernised terms "you shall not die, Jock, for any lass in all the land".Robert Chambers, Domestic Annals of Scotland, vol. 1 (Edinburgh, 1848), p. 244

Marie was a Catholic, and the earl was urged by the Kirk of Scotland to make her embrace the Protestant religion.Calendar State Papers Scotland, vol. 10 (Edinburgh, 1936), p. 773, 778, 780: for the banns see Stirling old parish register, 17 September 1592: for costume see NRS E35/14. In 1609 a marriage was planned between their son John Erskine and Jean Hay, daughter of the Earl of Errol who was thought to be Catholic. The king asked the Earl of Mar for Jean to make her profession of faith before the church, before the marriage. After the marriage she should be instructed and taught "according to that president whiche you haif alreddy kyithed in your owne wyife" - that Jean Hay should be taught the Protestant religion as Marie had been.HMC Mar & Kellie vol. 1 (1904), p. 65.

Marie was instructed by the minister of Stirling, Patrick Simson (1556-1618).Archibald Simson, A godly and fruitful exposition on the twenty five psalme (London, 1622).John McGavin, "Spectatorship in Scotland", Janet Hadley Williams & J. Derrick McClure, Fresche Fontanis (Cambridge Scholars, 2013), p. 292.

Marie was considered an excellent convert. James Caldwell minister of Falkirk dedicated his The Countesse of Marres Arcadia, or Sanctuarie Containing morning, and evening meditations, for the whole weeke (John Wreittoun: Edinburgh, 1625), to her, including a dedicatory letter by P. Anderson mentioning that "The Countesse of Pembroke's Arcadia is for the bodie; but the Countesse of Marre her Arcadia is for the Soule", and "amongst the many Noble Ladies of this Kingdome, your Honour to bee a true Paterne of modest Pietie, a perfect mirror of feminine gravitie, & a liberall supplier of the necessities of the poore, yea, in time of dearth, and scarsetie: And as his Majestie long since, in his Booke of Poesies, called your Noble Father the Phoenix of al the Nobility; so may the world esteeme your Honour to be another elect Lydia of that same Noble qualitie". The reference is to Lydia of Thyatira, an early convert to Christianity.

Faction in Scotland Marie Stewart was at court in May 1593, with her sister Henrietta, Countess of Huntly, and on 31 May with Anne of Denmark and the ladies of the royal household went to Leith to inspect the ship of the Danish ambassadors Niels Krag and Steen Bille at Leith, and rewarded the sailors with gold coins.Michael Pearce, "Anna of Denmark: Fashioning a Danish Court in Scotland", The Court Historian, 24:2 (2019), pp. 138-151, p. 150. : Calendar of State Papers Scotland, vol. 11 (Edinburgh, 1936), p. 94 no. 63: Acta Legationis Scotica, 1593: A journal of the Danish embassy 1593 (Latin), p. 17, Rigsarkivet

Marie was involved in factional politics, supporting her husband and also the cause of her sister and the Earl of Huntly.Ruth Grant, 'Friendship, Politics and Religion', in Miles Kerr-Peterson & Steven J. Reid,James VI and Noble Power (Abingdon, 2017), pp. 69-70.
