Since librarians are good at finding things (and people), you might want to consider adding Google Person Finder to your database.
Here's info on the API, which is now available via open source.
Google has a crisis response group that quickly went into action after the quake in Haiti in January, coordinating with groups internally and externally, including governmental and non-governmental authorities. A crisis response page was soon posted at here.
It was realized there would be a need for a way to find out the status of family and friends who may have been impacted by the quake. As groups began to coalesce around this need, it was discovered that a Person Finder application had been created in the aftermath of the WTC attacks in 2001. Another was created in response to hurricane Katrina. Unfortunately, a quick survey showed these applications could not be revived in a short time.
However, they have since worked out the kinks and created a viable program. Google now cordially invites you to work with them in a coordinated effort to help the crisis relief efforts for the people of Haiti.
