Maggie was born and raised in Monongah by her father Earle, with her mother, a suspected chem addict, leaving the family early on. After her father and some of his miner colleagues got trapped inside Monongah Mine, due to Deke Sykes blowing up the entrance in January 2076, she tried to gain entry to the mine to search for her father, but was unsuccessful. Due to her past experiences with the Hornwright family, who engaged in unfair worker practices, she is wary towards the only surviving member, Penny, and remarks that Penny's current ghoulish appearance is a reflection of who is she as a person.

↑Vault Dweller: "Are you from Monongah?" Maggie Williams: "Yep, born and raised in that dying mining town. I was glad to leave that shithole, especially after what happened to my pops." (Maggie Williams' dialogue)
↑Vault Dweller: "How did he end up in Monongah Mine?" Maggie Williams: "He and some other townsfolk got some liquid courage one night and decided to go up to the mine. I knew that damn bourbon would be the end of him somehow. They kept goin' on about getting the last of what they could before that Deke Sykes from Hornwright Industrial closed up the mine. Well, that son of a bitch ended up blastin' the entrance closed with everyone still inside." (Maggie Williams' dialogue)
↑Vault Dweller: "Why didn't anyone try to get them out?" Maggie Williams: "You don't think I tried?! I clawed at the rubble until my hands bled and they had to drag me away. They told me that my pops ran off, and said the others left Monongah since there was no more work. I think it was some sort of cover up. They either got paid off by the Hornwrights to keep quiet, or they didn't want to deal withe the expenses of a rescue mission." (Maggie Williams' dialogue)
↑Vault Dweller: "You know Penny Hornwright is in Foundation, right?" Maggie Williams: "Yeah, I know she's in town. I've been keeping an eye on her. Shame about her face... I guess the Hornwright's ugliness is finally showin' up on the outside." (Maggie Williams' dialogue)
