Clones of the telepathic Emma Frost, they are mentioned to be former students on the Massachusetts Academy on the novelization of X-Men: The Last Stand. There's an absence of the other remaining Cuckoos, Esme and Sophie. The triplets were seen behind Professor X and Storm. They appeared right after Hellion did in the background.
