<P> Megan "Meg" Griffin (voiced by Lacey Chabert in season 1, Mila Kunis since season 2) is the Griffins' 18 - year - old daughter and oldest child . She is a self - conscious, unattractive, sensitive, and emotionally fragile teenager who is more often than not ridiculed and ignored by the people around her . Meg just wants to be another face in the crowd by fitting in with her peers and being accepted, but she often finds herself to be a victim of circumstance . She has had several love interests over the course of the series, including Brian Griffin, Mayor Adam West, Tom Tucker, Glenn Quagmire, and Joe Swanson . </P> <P> Christopher Cross "Chris" Griffin (voiced by Seth Green) is the Griffins' 15 - year - old son and middle child who, like Meg, is a teenager . He is friendly, outgoing, funny, and good - hearted . A recurring gag is that an evil monkey lives in his closet which he finds out is not evil in the episode "Hannah Banana". Physically, he is a younger version of Peter, but intellectually, he more often than not shows better potential and is more idealistic, as demonstrated from moments of coherence and articulation within his speech, especially when talking about films, TV series, actors and actresses, etc . </P> <P> Stewart Gilligan "Stewie" Griffin (voiced by Seth MacFarlane) is the Griffin's 1 - year - old child, but often behaves in adult ways such as speaking in an upper - class British accent . He is a child genius who frequently aspired to murder his mother Lois and take over the world but has since mellowed out considerably . Stewie built a time machine with which he and Brian have traveled through time . He turned 1 year old in "Chitty Chitty Death Bang," and has not aged past one year since . As a fact in "Road to Rupert," he says he is a year old . </P> <P> Brian Griffin (voiced by Seth MacFarlane) is the family's anthropomorphic talking white Labrador Retriever and the best friend of both Stewie and Peter . He and Stewie are often at the center of the show's most critically acclaimed episodes, most notably the "Road to ..." episodes, where he and Stewie go on road - trips together . Brian is portrayed as an intellectual--a Brown University attendee--who often serves as the family's voice of reason, pointing out how ridiculous Peter's ideas are . He is not - so - secretly in love with Lois and is an unsuccessful, unemployed writer . </P>
