Los Angeles-based genealogy and family networking site Geni has rolled out a new "Family Finder" feature, the firm said Friday, allowing users to import addresses from Microsoft Outlook, web email programs like Google's Gmail and Yahoo, or other sources. According to Geni, the new feature will look through your address book and select anyone that the company's software thinks is related to you. The new feature also allows Geni users to invite other contacts to share photos, videos, and events. Geni operates a Web 2.0 web site that allows users to create a family tree and share family information, events, and more. Geni was started by former PayPal founder David Sacks, and is venture backed by the Founders Fund and Charles River Ventures.
