Chloe Mitchell [SEP] Introduction
Chloe Mitchell is a fictional character from "The Young and the Restless", an American soap opera on the CBS network. Introduced by former executive producer Edward J. Scott as the daughter of trusty Chancellor family maid, Esther Valentine (Kate Linder), the character was born onscreen on July 27, 1990. Originally portrayed by twins, Darla and Sandra Greer, until 1991, upon her brief return in 1994, child actress, Danielle Ryah, portrayed the role. On February 6, 2008, executive producer/head writer Josh Griffith introduced a new character, Chloe Mitchell, played by former "All My Children" actress, Elizabeth Hendrickson. That August, a change in storyline revealed Chloe was Kate, having legally changed her name while offscreen, when the character was away in boarding school.
