First of all I am sorry you have to go through this to track her down. I would not start the second one until I have made contact with someone either her or her family. Go back to the beginning of how she found you. That would be the first way to track her. There maybe someone would know what is going on. Another thing you may want to do is vet these quilts with all the information you know about them going as far back as you were told with names dates weddings and so on. The history tells the story when all else may be lost. Let the history live on. Hopefully you will be able to find her of family soon.
