In May 1622 at
Whitehall Palace her son
James, Earl of Home, married Catherine Cary daughter of
Henry Cary, 1st Viscount Falkland (c.1575 – 1633) and
Elizabeth Cary née Tanfield.
John Chamberlain noted that the marriage had been arranged by the king. In Scotland, before the wedding, following the king's instructions, the lawyer
Thomas Haddington convened a meeting of the six lairds of the Home surname to tell them about the marriage plans. They promised to help the earl, but had reservations, hoping that Lady Home would "make her intentions and courses known to them" and she would "hear and respect their faithful advice" concerning the earl, and if she neglected to consult them, they could have "no contentment in the business." In December, Lady Home wrote to Leonard Welstead, an agent of Lord Falkland (and formerly, with
Matthew Lister, a trustee of the
Countess of Pembroke), about dowry payments, and the toothache suffered by Lord Home and Catherine. After Catherine's death in childbirth in 1625, James married Grace Fane, daughter of
Francis Fane, 1st Earl of Westmorland (1583/4–1629). James still had legal guardians called "curators" including the
Earl Marischal, the Earl of Morton, and
Sir Robert Kerr of Ancram, a
gentleman in the king's bedchamber. Mary wrote to Morton (who was in England) for help over dowry payments, wanting an installment of £1000 Sterling cash sent to her in Scotland rather than allow the Earl of Westmorland to invest the money in a project in England and buy land. She hoped the rest of the curators would agree with her, deferring to their "wiser judgements" but insisting "I will bee the last consentor to such a bisnes". She wanted the cash for dowries for her daughters.
Mary Mildmay Fane, Countess of Westmorland wrote letters to her daughter Grace in Scotland solicitous of her health, including passages in cipher, one referring to loss of her hair through illness. She hoped Grace would come to London to take her sisters to see the masques at court in 1631, ''
Love's Triumph Through Callipolis and Chloridia''. Grace was treated by an Edinburgh physician, David Arnot. James Home died in London in February 1633, attended by the court physician
Théodore de Mayerne, and Grace died soon afterwards at Apethorpe. The two countesses continued a bitter lawsuit over their children's properties. Westmorland was her daughter's executrix. She complained that the Countess of Home had the advantage in Scottish courts from her continual residence and acquaintance in Edinburgh. Charles I wrote to the
Court of Session in Westmorland's favour on 5 May 1634. The earldom passed to a distant cousin
James Home, 3rd Earl of Home (1615–1666). Mary wrote to Sir David Home of Wedderburn from Aldersgate after her son's death about the future of the Home family, name, and "ancient raice", asking him to "express your love both to the living and to the dead".
Lady Moray and Lady Lauderdale A Scottish author
Patrick Hannay (fl. 1616–1630) dedicated
A happy husband or, Directions for a Maide to choose her Mate, As also, a Wives behaviour towards her Husband after Marriage (Edinburgh, 1618/1619?) to Mary's eldest daughter Margaret Home (d. 1683), who married
James Stewart, 4th Earl of Moray in 1628. Hannay's title refers to Sir
Thomas Overbury. The Earl of Moray's main residence near Edinburgh was
Donibristle House. The Countess of Home and the Earl of Moray are said to have refused to contribute to building a new church at
Beath in Fife in 1640. In 1632 Mary's younger daughter
Lady Anne Home married
John Maitland later
Duke of Lauderdale. Anne inherited her mother's properties and furnishings in London.
Lady Home's will Mary made a will in 1638 reflecting her English and Scottish properties and identity. She hoped her granddaughters would inherit her furnishings and collection, dividing house contents in London and Scotland between them, according to the inventories of each house. She was aware that this was problematic, writing "And I am not ignorant that my houses both in Edinborough as Canongate and in Aldersgate Street being inheritance I cannot dispose so of them by this my late will neither by the laws of England nor Scotland". Amongst personal bequests to her family and servants, she left a purse of gold coins to her nephew,
Frederick Schomberg, 1st Duke of Schomberg, the son of her sister
Anne (Dudley) Sutton. The will appointed her granddaughter
Lady Mary Stewart (d. 1668) as executor, but she was still a minor when the countess died in London in March 1644, and resigned her rights as an executor on 24 May 1645. Lady Moray and Lady Lauderdale and their husbands instead acted as executors and "administratices". Her body was shipped to Scotland and buried at Dunglass. An account of the financial settlement to 31 March 1646 was made by the merchant financier
Robert Inglis.
The will and the Commonwealth In 1648 Lauderdale's share of her possessions and furniture in London was forfeited by his
delinquency and sold. Claims that the furnishings belonged to his daughter or had been sold to a Scottish merchant in London,
Robert Inglis, were disregarded. Some goods at Aldersgate were sold in October 1648. It also came to light that Mary had lent £2,000 to the
Earl of Cleveland and obtained property in Hackney and Stepney, and £1000 to Elizabeth Ashfield, a neighbour in Aldersgate, gaining her lands at North Barsteed in Suffolk. A challenge to the administration of the will by a third-party William Dudley, demonstrating that goods belonged not to Lauderdale but to his daughter, and that the executors had not been lawfully appointed, failed in 1658. Lauderdale was enabled to recover his property at the
Restoration. It is due to the complexities of dividing her goods and this legal battle that her inventories survive to give a unique insight into the material culture of Anglo-Scottish aristocrat in the 1630s. The inventories include a set of portraits after
Van Dyck now at
Darnaway Castle. ==Children==
