Notes:

Sir Archabald Douglas the first son and heir of Alexander Douglas became the 10th Larid of Mains. His wife was Isobel of Blyswood, married 22 July 1633. He died 1 July 1647 leaving his entire estate to his wife. Due to heavy debts, the landed estate of Mains was deeded over to John Douglas, a relative. At this time Mains stayed in the Douglas family but passed to another Douglas line.

Sir Robert obtained Blackerston by marriage. He purchased Blythswood. It should be noted that Col. John Douglas's plantation in Maryland was named Blythswood (Blythswood) the name of the Manor in Scotland.

Sir Robert, as did most Scots, suffered greatly from the ravages of Oliver Cromwell. This was the primary cause of his financial problems along with a default , of the city of Glasgow, on money owed to him.

Robert married Lady Susanna Douglas on 3 Feb 1635 in St. Andrews Church At Holborn, England. Susanna (daughter of Robert (Viscount Belhaven) (of Spot) Douglas and Elizabeth Whalley) was born about 1617 in London, England; died about 1692 in London, England. [Group Sheet] [Family Chart]

Notes:

Susan Douglases birth was legitimized on 30 July 1631, by Royal Decree, when she was thirteen years old. This would put her date of birth at 1617 or 1618.
Presumably Nicolas was not her mother.

Married:

Alexander married Grizel Henderson in 1618. Grizel died in 1618. [Group Sheet] [Family Chart]

He was afterwards Master of the Household and a member of the Privy Council, and in 1633 he was by patent created Viscount Belhaven, in the Peerage of Scotland. He died without issue, 14th January 1639, in the sixty-sixth year of his age. He was buried in the chapel of Holyrood House, where his monument is still to be seen, and upon which was carved an epitaph giving an account of his "remarkable actions."
