Over the course of "Grey's Anatomy's" nine long seasons, Meredith Grey has run the gamut of family problems. Her absent mother Ellis had Alzheimer's and died, her father Thatcher left their family when she was young and remarried, and his daughter Lexie sought to reconnect with Meredith against the elder Grey sister's will. Then, when they did finally become friends, Lexie tragically died in a plane crash. All those issues don't even touch on the problems Meredith went through with her one night stand-turned-boyfriend-turned husband Derek Shepherd and their struggle to have a child.
