Frieda is not originally from Hoover Dam. She hails from Redding, and was born into the Van Graff family. She was born to Tiaret Van Graff, and is the sister of prisoner Jean-Baptiste Cutting. She knows very little about her half-brother, except that he has been missing for a few years now.
Frieda is attractive, but she is very hard, like an old bar-fly. She doesn't take crap from anyone and would just as soon shoot you as to serve you. She expects a courteous customer, and if she doesn't feel respected, she refuses to do business until the customer changes their ways.
Frieda has not appeared nor is she mentioned in any published game, however other members of the Van Graff Family are present in Fallout: New Vegas. She was to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if she will appear in any future Fallout game.
