Clementine was the the daughter of James "Sawyer" Ford and Cassidy Phillips.
She was portrayed by Olivia Vickery in the Season 5 episode
"Whatever Happened, Happened".
Her mother Cassidy Phillips was portrayed by Kim Dickens.
There isn't a dedicated entry for Cassidy in
The LOST Encyclopedia, so I'm including her with Clementine.
(personal editorial: They included "Airport Guard", but not Cassidy Phillips?
I have serious issues with some of the character omissions.)
My collection includes a Rittenhouse LOST Archives Autograph card...
Rittenhouse LOST Archives Character card #47
....and a 10"x8" photo signed by Kim Dickens.
