I've spent quite a few hours on this case this week, but I keep hitting dead ends. I am unable to find any confirmed marriage records for her, unable to find a photo, unable to find any further info on her case. I am still looking though...
I only have a newspaper.com subscription, which doesn't have any archive of the New Haven Register, which is where her parents' obituaries were published (I know this via FindaGrave) so I wonder if any articles about her disappearance might be in that paper alone. Looks like GenealogyBank has the archive of that paper, if anyone has a membership and is interested in looking there!
