Flora Curzon, Lady Howe (born Florence Hamilton Davis; January 27, 1870 – April 15, 1925), was an American heiress and singer who twice married into the British aristocracy.

[6] In 1898, her father, who was as "conspicuous in society as he [wa]s in Wall Street," married for the third time, out of four overall, to South African born Mary Ethel Jackson, a friend of Flora's who was about thirty-three years his junior.

When her husband, then Lord Terence Blackwood, was Secretary to the British Embassy at Paris, she frequently sang in private salons in the cause of charity.

"[8] On October 16, 1893, Flora was married to Lord Terence Hamilton-Temple-Blackwood at the English Church of the Holy Trinity in the Avenue de l'Alma in Paris.

Lady Howe died of heart disease following influenza and pneumonia at Penn House, Amersham, Buckinghamshire, on 14 April 1925.
