Good news! I just received an email from the woman who responded to my Craigslist posting. She finally heard from the family she had asked me to help her find--they are okay; they had been in the Superdome, and were evacuated by bus to Texas. She said they'll be there for a couple of months. I am so relieved. I had been combing the online data bases for their names daily, and felt such a rush of despair when nothing turned up. Here's to more successful searches, more happy endings in the midst of so much tragedy.
