McSwiggan Village is a stereotypical small Irish village and the home of Mickey McFinnigan, Peter's biological father.

Peter and Brian visit this village in search for Peter's father in "Peter's Two Dads". According to one of the residents, "the hills are green, the streams are clear, and the sweaters are so thick, even the boniest finger nun could poke you in the chest and it wouldn't bother you none."

Wifey McBeaty’s Tavern is the local pub and the town's meeting point.
