Peter Griffin is the obnoxious, boisterous man who is the protagonist of the show and origin of the title "Family Guy". He's a man of Irish descent currently residing in Quahog, Rhode Island with his wife Lois Griffin. He was, however, born in Mexico, where his mother had tried unsuccessfully to abort him. They have three children, Chris, Meg, and baby Stewie. After a mix up at a sperm bank, Peter also became the biological father of Bertram. Out of pity he also adopted an intellectual talking dog named Brian who formerly lived on the street as a stray (there are two stories of how Brian got to be adopted).
