Every year following the Sept. 11, 2001, attacks brings us new information: tiny tidbits of personal stories that perhaps we hadn't read before, or saw on the news, or heard from an old friend we haven't seen in umpteen years. Every year, our mass connection to these chapters—these parts of a whole—brings us all a little closer to the full story, and to each other.

As they say, there are a million stories in the Big City and we can never know them all. And so we may never know all the stories of the smaller city within New York that was the World Trade Center. So it was with some surprise this morning when I read that my former classmate, Ginger Ormiston, had been an employee at Marsh & McLennan.

It was only last year that I learned she was killed in the World Trade Center attacks. A former classmate posted a photo on Facebook of her name, engraved in granite, at the WTC Memorial site. Until then, I had no idea.
