Although 13 years older, Harriet was Queen Victoria's best friend. She was Mistress of the Robes and lived at grand Stafford
House (now Lancaster House
. When visiting Harriet's home, Victoria would say,
"I've left my house to visit your palace."
Harriet's husband, the 2nd Duke of Sutherland, passed away in 1861.
was widowed later that same year. According to The Times,
Harriet Sutherland 'was admitted by her Sovereign to a friendship so close and personal that on the death of the Prince Consort she was
the one guest at Windsor Castle in whose company the Queen spent the first weeks of her sorrow and seclusion.'
Unlike most of the British aristocracy, Harriet favoured the Union during the American Civil War. The anti-slavery meetings she hosted caused
her critics to refer to palatial Stafford House as 'Aunt Harriet's Cabin', a play on 'Uncle Tom's Cabin'.
Harriet only lived to age 62, passing in 1868. In 1871 one of her grandsons married Victoria's daughter, Princess Louise. In 1885 Queen Victoria
stood godmother to Harriet's great-granddaughter, Victoria Elizabeth, daughter of the 4th Duke of Sutherland.
She only lived to age two. Three of Harriet's descendants had the Queen as godmother and did not survive infancy. One wonders if
Queen Victoria felt jinxed in this capacity.
