London, August 18 : Dungeon girl Elisabeth Fritzl, 42, has turned down Austrian officials' offer to change the identify of her cellar family completely.
She has plans to switch just their surname, according to reports.
Elisabeth will set up home with her six children-fathered by her own father Josef who repeatedly raped her during the 24 years locked up underground-in a secret location just an hour from Amstetten, where her ordeal took place.
Insiders say that the family will move out of the Amstetten-Mauer psychiatric clinic after Fritzl's trial in December.
"Elisabeth knows people will put two and two together. She has pretty much ruled out new identities. It's likely they will just change their surname," the Mirror quoted a source at the clinic as saying. "It'd be impossible to transform seven individual profiles unless they moved to the other side of the world," the source added.
