Muriel Ashley, Baroness Mount Temple

Muriel Emily Ashley, Baroness Mount Temple (née Spencer, formerly The Hon. Mrs. Arthur Forbes-Sempill; 1881 – 24 June 1954), also known as Molly Mountemple, was a British aristocrat. She was first married to Arthur Forbes-Sempill, a military officer and younger son of William Forbes-Sempill, 17th Lord Sempill. After their divorce in 1914, she married Wilfrid Ashley, who would later be created Baron Mount Temple in 1932. As the wife of Lord Mount Temple, she was the stepmother of Edwina Mountbatten, Countess Mountbatten of Burma and Mary Cholmondeley, Baroness Delamere. She was unpopular with her stepchildren, and described as "wicked" and "unkind" by friends of the family. She managed the family's estate Broadlands and two London town houses in Westminster. A bathroom in their second town house, done in the Art Deco style, was called "Lady Mount Temple's Crystal Palace" by the British press.
