Peter Griffin (voiced by Seth MacFarlane) is an "average" American father. Peter is irresponsible, obese, immature, loud-mouthed, dim-witted and a heavy drinker. He finds out he is mentally retarded in the episode "Petarded".

Lois Griffin (voiced by Alex Borstein) is Peter Griffin's wife. She is a stay-at-home mother who juggles her piano lessons, kids, and husband.

Meg Griffin (voiced by Rachael MacFarlane in the pilot, Lacey Chabert in the first season, Mila Kunis in later seasons) is the Griffins' eldest child and only daughter. She is a self-conscious teenage girl. The other family members treat her with contempt, as an object of abuse, and an outcast. Meg often attempts to "fit in" with the popular kids but is rejected. Meg has had several love interests, including the Griffins' dog Brian.

James Joseph "Jim" Croce (/ˈkroʊtʃi/; January 10, 1943 – September 20, 1973) was an American singer-songwriter. Between 1966 and 1973, Croce released five studio albums and 11 singles. His singles "Bad, Bad Leroy Brown" and "Time in a Bottle" were both number one hits on the Billboard Hot 100 charts.

Croce was born in South Philadelphia, Pennsylvania, on January 10, 1943, to Jim and Flora Croce, and grew up in a family of Italian background. Croce took a strong interest in music at a young age. At five, he learned to play his first song on the accordion, "Lady of Spain."

Croce attended Upper Darby High School in Drexel Hill, Pennsylvania. After his graduation in 1960, Croce went to Malvern Preparatory School for one year before deciding to enroll at Villanova University in 1961. During his time as a student, Croce became a member of the Villanova Singers and the Spires. When the Spires performed off-campus gigs or made professional recordings, it was under the name, "The Coventry Lads". Jim was also a student disc jockey at WKVU.
