She had such distinctively crooked teeth that it should be easy to find her skull if it is really in some storage or archive. Ive worked in big archeological archives and while there were some boxes with old finds pre 1960, they were still somehow labeled at least with location and type of artifact and most had inventory numbers.
Also no archive is endless, just check the boxes that are not clearly labeled and among those search for bones and a skull. Shouldnt take more than 1-2 weeks. I mean, really.
