Euphemia (Effie) Gray was born in Scotland in 1828. She married the Victorian art critic John Ruskin. The marriage was never consummated. After annulling the marriage, she married the pre-Raphaelite artist John Everett Millais and had eight children. (Borrowed this from Rose-Berry's entry for "Effie" with a slight change in wording.)
