about
Dialogue in the episodes "Tracy Does Conan" and "Jack Meets Dennis" suggest Liz was born around November, 1971. In "Jack Meets Dennis", she stated that she was from somewhere called "White Haven," possibly referring to White Haven, Pennsylvania. This conjecture is strengthened by the fact that she mentioned in "The Source Awards" that her name, misspelled as "Lez", appeared on a scoreboard at Phillies game when she was eight, this being more likely to occur if she were from Pennsylvania. Tina Fey is from Pennsylvania.
Little has been revealed about Liz's family, but she mentioned a brother named Mitch in "The Rural Juror" and in "Fireworks" she stated that her mother used to use their vacuum to drown out the sound of her fighting with her husband. Consequently, the sound of a vacuum still makes Liz anxious and she therefore rarely vacuums her apartment. In "Jack Meets Dennis", she mentions that Dennis has been asking her mother for money, indicating that Liz's mother is, at the very least, still alive. In college, Liz, as mentioned in "Black Tie", studied theater tech and in "Jack the Writer" she mentioned that she used to teach improv to senior citizens. Liz and Jenna Maroney knew each other well as early as 1996 and together dreamed of making it big. They shared an apartment in a Chicago neighborhood called "Little Armenia" and began The Girlie Show on Second City. At that time, the show apparently starred both of them. Liz and Jenna worked for years to turn The Girlie Show into a television series, the pair of them even having to move from Chicago to New York City for it. Liz became the head writer and apparently the unofficial show runner for The Girlie Show while Jenna became the show's main star. It is not known when the television version of The Girlie Show started, but it was apparently after the year 2000 and the show had evidently run long enough to successfully find a fanbase by the time of the pilot episode. Liz and the writers apparently had a good relationship with their boss Gary, who was stated to love the show and be pleased with the ratings. However, Gary's death is announced in the pilot and Jack Donaghy takes his place. Jack immediately decides to retool the show to make it appeal to a larger demographic, starting by firing Liz's trusted producer Pete Hornberger and making her hire unpredictable actor Tracy Jordan as the show's new star. Liz manages to convince Jack to re-hire Pete, but Jack is insistent on making the show center around Tracy and, much to her chagrin, he renames the show TGS with Tracy Jordan. Liz currently lives in an apartment at 160 Riverside Drive, which is a real apartment complex in New York City. As shown in "The Break Up", her apartment number is 3B. Although Riverside Drive is quite a distance from her workplace at 30 Rock, she is reguarly portrayed walking to work. Source: Wikipedia
