Edith Maud Rawdon-Hastings, 10th Countess of Loudoun (10 December 1833 – 23 January 1874) was a Scottish peer, the daughter of George Rawdon-Hastings, 2nd Marquess of Hastings and his wife Barbara née Yelverton. She was greatly attached to the old Mure family mansion of Rowallan Castle near Kilmaurs in Ayrshire. She expended considerable sums in repairing the ancient edifice and without her concern this remarkable building would no longer be with us.
On 30 April 1853, she married Charles Clifton, who took the name Abney-Hastings, as a condition of inheriting from a second cousin Sir Charles Abney-Hastings, 2nd Bt, a natural grandson of the 10th Earl of Huntingdon (brother of Lady Edith's grandmother). They had six children:
Lady Flora Paulyna Hetty Barbara Abney Hastings (1854–1887), married Henry Fitzalan-Howard, 15th Duke of Norfolk and had issue.
Charles Edward Hastings Clifton, 11th Earl of Loudoun (1855–1920)
Major Paulyn Francis Cuthbert Rawdon-Hastings (1856–1907), married Lady Maud Grimston, daughter of James Grimston, 2nd Earl of Verulam and had issue, including Edith Abney-Hastings, later 12th Countess of Loudoun.
Gilbert Theophilus Clifton Clifton-Hastings-Campbell, 3rd Baron Donington (1859–1927)
Henry Cecil Plantagenet Clifton (1860–1886), died young.
Lady Egidia Sophia Frederica Christina Clifton (1870–1892), died young.
After her death her widowed husband was created Baron Donington.
