Alexander Murray, 6th Earl of Dunmore
Alexander Edward Murray, 6th Earl of Dunmore( 1 June 1804 – 15 July 1845) was the son of George Murray, 5th Earl of Dunmore.
On 27 September 1836 in Frankfurt, Germany, he married Lady Catherine Herbert, daughter of the 11th Earl of Pembroke.
They had four children:
Lady Charlotte Murray
Lady Charlotte Murray (2 August 1754 – 4 April 1808) was a Scottish botanist and author.
She was the eldest child of John Murray, 3rd Duke of Atholl, and Charlotte Murray, Duchess of Atholl.
Her paternal grandfather was the Jacobite general Lord George Murray while her maternal grandfather was the Hanoverian James Murray, 2nd Duke of Atholl.
She is best known for her two-volume work "The British Garden", which ran to two or three editions in her lifetime, the second (and possibly the first) being in 1799, and the third in 1805 or 1808, and another in 1880.
The book was targeted at young people and considered the Linnaean system and how it can be used to discover the name of an unknown plant.
In 1793, Lady Charlotte discovered a double variety of "Geranium pratense" which she sent to Lady Banks.
She died in Bath on 4 April 1808, unmarried.
Charles Gordon-Lennox, 6th Duke of Richmond
Charles Henry Gordon- Lennox, 6th Duke of Richmond, 6th Duke of Lennox, and 1st Duke of Gordon,( 27 February 181827 September 1903), styled Lord Settrington until 1819 and Earl of March between 1819 and 1860, was a British Conservative politician.
Anne Murray, Duchess of Atholl
Anne Murray, Duchess of Atholl( 17 June 1814 – 22 May 1897), born Anne Home- Drummond and known as The Lady Glenlyon between 1839 and 1846, as The Duchess of Atholl between 1846 and 1864 and as The Dowager Duchess of Atholl between 1864 and 1897, was a Scottish courtier and close friend of Queen Victoria.
Murray was born at Edinburgh, Scotland, the daughter of Henry Home- Drummond, of Blair Drummond, by Christian, daughter of Charles Moray.
On 29 October 1839 she married George Murray, 2nd Baron Glenlyon, at Blair Drummond, thereby becoming Lady Glenlyon.
In 1846 he succeeded his uncle as sixth Duke of Atholl, and Anne became Duchess of Atholl.
She served as Mistress of the Robes to Queen Victoria in Lord Derby's short- lived government of 1852.
She subsequently served the queen as a Lady of the Bedchamber for almost forty years and was one of Victoria's closest friends.
When The Prince Consort died, the Queen came out of the room where he had died and proclaimed," Oh, Duchess, he is dead!"
The Duke of Atholl died in 1864, and Anne became the Dowager Duchess of Atholl.
In 1892, when Gladstone again came to power, his policy of Home Rule for Ireland had alienated many of the upper classes, and no lady of ducal rank could be found who was willing to serve as Mistress of the Robes.
The post therefore remained vacant, while the Dowager Duchess of Atholl and the Duchess of Roxburghe performed the duties of the office.
The duchess and her husband preferred the spelling" Athole" for their title and residence.
The Duke and Duchess had one child, John Stewart- Murray, 7th Duke of Atholl.
The Duchess of Atholl died at Dunkeld, Perthshire, in May 1897, aged 82, and was buried at Blair Atholl.

In 1844, when Queen Victoria stayed at Blair Castle, the Atholl Highlanders provided the guard for the Queen.
So impressed was she with their turnout that she ordered they be presented with colours, giving them official status as a British regiment.
On 29 October 1839, he married Anne Home-Drummond, daughter of Henry Home-Drummond.
Murray died in 1864, aged 49, from cancer of the neck and was succeeded in his titles by his only child John.
