You may have already thought of this, as this was the first other option to pop into my head.. if you have so much info on her, I assume you know her name and where she is located? If then, try searching at
www.whitepages.com with her name, city and state and perhaps a telephone number will be found for you.
Hope this helps. Also, is your daughter on AOL? There is a way to see if she has read your messages... but it's been so long since I've had AOL, I can't exactly remember how to do it
