Story
A devout Irish-American Catholic, Francis Griffin has had a rocky relationship with his stepson, Peter, over the years. However, he does love Peter, though he may not like him. Francis is extremely religious and honors Jesus, God and the Pope. However when the Pope comes to Quahog Francis deems him to be an untrue Catholic. All Francis believes in is work, work and more work which obviously leads to conflict with Peter. It is revealed after Francis' death that he was Peter's stepfather, not his biological father. In the episode 'Stu & Stewie's Excellent Adventure' he can be seen attending Chris' Future Wedding, even though he is dead. Due to canon in the series, it is possible that it is another man who resembles him. Also, he would logically not be alive in the future unless when Stewie stopped his near death experience, Francis Griffin's future was somehow altered (along with the futures of other characters) and he would not have originally died. His ghost reappears in Family Goy.
Although Francis loves Peter, he does hate Lois because she's Protestant in which why on the wedding day, he spray painted "To A Protestant Whore" underneath the "Just Married" sign on back of the limo. He also hit Brain with his bible for questioning it.
Though Francis is a Catholic, in the episode The Father, the Son, and the Holy Fonz he says that Peter's new religion was stupid, but at the end of the episode he is seen praying and kneeling for Arthur Fonzarelli, the character who Peter's religion is based on.

Death
- Francis died at the Quahog Hospital in the episode Peter's Two Dads. He suffered crushed ribs, busted spleen and a punctured lung after Peter fell down the stairs on a unicycle and landed on him.
- Francis was seen at Chris's wedding in the future, all though he died long before, however this was an alternate timeline.
Trivia
- Francis' death was the first event to make the movie's timeline void.
- Francis hates Lois just as Carter Pewterschmidt hates Peter. He also dislikes Brian like Carter does, although he did work with him to put some sense into Peter in The Father, the Son, and the Holy Fonz.
- In multiple episodes, Peter talks about his relatives and ancestors, all of which share the name Griffin, not McFinnagan. This makes little sense seeing that all these relatives have almost perfect resemblance to Peter. It is conceivable that the Griffins and the McFinnagans share a common ancestor.
