One of online genealogy’s newest kids on the block is proving to be a popular place. Geni.com reports its website has acquired 5 million profiles in its first 5 months of operation. The social networking site offers everything from sharing family trees to birthday reminders, a family calendar, messaging and photo sharing.

The Los Angeles-based site launched back in mid-January, allowing users a place to build their family trees and create profiles for the people in those trees. Geni.com says it’s already heard from many users who’ve found cousins around the world via the site.

“I believe we are reaching a tipping point where each incremental user is more willing to contribute data about his family relationships because so many other people have done so,” said David Sacks, CEO of Geni.com. “Our goal is to unite the world in a single family tree, and then help those family members learn about and stay in touch with each other,” Sacks said.

Because of the millions of profiles that users have contributed to Geni, the site is becoming a valuable genealogical reference tool. Thanks to Geni’s new search feature, users can search for a relative among millions of profiles in other family trees. If there is a match, the user can then message the person who added that potential common ancestor.
