Lady Georgiana was born in London, England, the youngest of 16 children in an aristocratic family. Her parents were Thomas Henry Liddell, 1st Baron Ravensworth, and his wife Marion Susannah. At age 19, she became a maid-of-honor to Queen Victoria, who was about her same age, and they maintained a lifelong friendship. In 1845, she married John Arthur Douglas, 2nd Baron Bloomfield, an Anglo-Irish diplomat, and accompanied him on his postings to St. Petersburg, Berlin, and Vienna. After her husband's death in 1879, Lady Bloomfield settled at Shrivenham in Berkshire, to be closer to her sister Jane, Lady Barrington. Following Lady Barrington's death in 1883, Lady Bloomfield moved to Bramfield House, about two miles from Hertford. That same year, she published Reminiscences of Court and Diplomatic Life (2 volumes). In 1884, she edited Memoir of Benjamin, Lord Bloomfield, her father-in-law. Her last work, Gleanings of a Long Life (1902), consisted of extracts from her favorite books.
