The following is an excerpt from an email message I received from Geni:

We are excited to let you know that Geni's World Family Tree now connects over 150 million profiles!

This huge milestone was possible thanks to the collaboration of over 13 million users and over 200 volunteer Curators from all over the world. The World Family Tree has grown faster than ever with over 11 million profiles added in the last year.

Geni’s World Family Tree allows millions of people to work together to research and preserve their shared ancestry for future generations. By combining research into a single shared family tree, users are able to concentrate on pursuing new leads instead of repeating the same research over and over again. Over time, the quality and accuracy of the tree continues to improve as new information is discovered, errors are corrected, and new connections are found. With more and more profiles added every day and overlapping branches merged, Geni has become one of the premier go-to reference sites for global genealogy.
