I think this girl http://www.cbsnews.com/pictures/seri...os-24-9-10/17/ has a little bit of a Danish or German look about her. But here are a few suggestions.

http://www.missingkids.com/poster/NCMC/601900/1 - Kathleen Shea (the girl looks about eight to me, so maybe. The photographs of Kathleen are in black-and-white, so it's hard to tell. It's something about the nose.)

http://www.missingkids.com/poster/NCMC/601237/1 - Christie Farni (I'm not ruling out that the hair could have been dyed.)

http://www.missingkids.com/poster/NCMC/1037093/1 - Melissa Highsmith (She was only a baby, so her hair may have gotten lighter.)
