Peter Löwenbräu Griffin I (born Justin Peter Griffin) is the patriarch of the Griffin family. He is an unconventional 45-year-old overweight, immature, unintelligent alcoholic Irish-American living in Quahog. He was born in 1954. He has held a number of blue-collar jobs, including as an employee of the Happy-Go-Lucky Toy Factory and shortly before his death, at the shipping department of the Pawtucket Brewery.
He was married to Lois Griffin (née Pewterschmidt). He was also the father of 18-year-old daughter Meg and sons, teenager Chris and one-year-old Stewie. His pet was a talking 8-year-old dog, Brian, who the family has had since he was a stray.
One of Peter's favorite pastimes was drinking beer, specifically Pawtucket Patriot Ale, usually at The Drunken Clam with his best friends Cleveland, Joe, and Quagmire.
Peter Löwenbräu Griffin was born in Mexico City, Mexico. His mother, Thelma, was in Mexico getting an abortion; however, during the procedure, Peter was born. After his birth, she took Peter back to Rhode Island where he was raised by his mother and adoptive father Francis in the Catholic faith. However, his mother had never filled out his citizenship papers, making him an illegal immigrant. According to his birth certificate, he was born Justin Peter Griffin in Quahog. After Francis' accidental death caused by Peter, Peter discovered his biological father is Mickey McFinnigan, an alcoholic from Ireland.
Peter's personality traits tended to change from day-to-day. He was, for the most part, an inconsiderate, obnoxious person with a childish sense of humor. Despite these negative traits, Peter had also been consistently shown to be a loving, caring man who truly loves his friends and family above all else. Peter's hobbies tended to be much more consistent, he loved to drink beer, watch TV and films, listen to music and masturbate, and from time-to-time, he'd shown a keen interest in video games. Peter appeared to be a fan of science-fiction, especially Star Trek and comic book movies like Superman and Batman. Additionally, Peter had shown an interest in space and space travel on a handful of times, even going as far as to buy his own space-shuttle.
