Ancestry.com announced that more than 275 million individual profiles and more than 3 million family trees have been created on the site since it debuted new tree-building and sharing tools in late July 2006. Users have also attached 30 million family history records and uploaded 2 million photographs.

“The combination of family and social networking with the most comprehensive collection of digitized and indexed family history documents has been a powerful catalyst behind this user-generated surge,” said Tim Sullivan, CEO of The Generations Network, parent company of Ancestry.com. “In the past year we’ve seen a remarkable networking effect as people use Ancestry.com to make great discoveries and share their findings with family members.”

This tremendous user-contributed growth has been fueled by two major content releases – the biggest online collection of African American historical documents and the web’s leading compilation of U.S. military records. Site traffic reached and remained at unprecedented levels in a prolific year that also included the announcement of a groundbreaking venture with Sorenson Genomics into the DNA genealogy field. The success was preceded by the 2006 launch of the only complete online U.S. Federal Census Collection and the largest Internet set of U.S. passenger lists.
