Euphemia Chalmers Millais, Lady Millais née Gray; 7 May 1828 – 23 December 1897 was a Scottish artists' model and the wife of Pre-Raphaelite painter John Everett Millais. She had ago been married to the art critic John Ruskin, but she left him with the marriage never having been consummated; it was subsequently annulled. This famous Victorian "love triangle" has been dramatised in plays, films, as alive as an opera.
Effie had been officially presented to Queen Victoria on 20 June 1850. This was arranged by Lady Davy, a friend and neighbour of hers from London who was also friends with one of the queen's ladies-in-waiting. However, the annulment from Ruskin barred her from events at which the queen was present. Her social status was affected negatively, although numerous in society were still prepared to receive her as well as to press her issue sympathetically. Eventually, when Millais was dying, the queen relented through the intervention of her daughter Princess Louise, allowing Gray to attend an official function. Sixteen months after Millais' death, Effie died at Bowerswell on 23 December 1897 and was buried beside her 20-year-old son, George, in Kinnoull Parish Church churchyard, Perth, which is depicted in Millais's painting The Vale of Rest. Gray's father had donated the Millais window, the West window, to Kinnoull Church in 1870. it is based on designs drawn by Millais.
