Today marks two years since a massive earthquake ravaged Haiti, leaving 300,000 dead and millions homeless.  Two years later, many Haitians remain in tent camps and makeshift shelters. Billions of dollars in international aid has yet to be disbursed. NBC News Correspondent Ron Allen recently returned to the country to follow up on an American family who adopted two Haitian girls, Naika and Tia. The family, Mike and Missy Wilson, remain committed to the country, visiting more than a dozen times since the quake.  They are building an orphanage in Haiti.  Below are photos from Allen's journey.
