The opening as it read in 2015

Agnes Keyser , RRC (1852 – 11 May 1941) was a humanitarian, courtesan and longtime mistress to Edward VII of the United Kingdom .1 Keyser was the wealthy daughter of a Stock Exchange member, and of all of Edward VII's mistresses, with the exception of socialite Jennie Jerome , she was the best accepted within royal circles, including by Edward VII's wife, Alexandra of Denmark . She remained with Edward VII until his death in 1910.2 Keyser, as recorded by author Raymond Lamont-Brown in his book Edward VII's Last Loves: Alice Keppel and Agnes Keyser , held an emotional bond with Edward VII that others did not, due to her being unmarried herself, and preferring a more private affair to that of a public one. Keyser was born Elizabeth Agnes Keyser in July 1852 at Great Stanmore in Middlesex, the daughter of Charles and Margaret Keyser. Her father was a partner in a stock exchange firm Ricardo and Keyser.3
