WikiTree.com

What makes WikiTree.com special is its unique Trusted List system. Unlike most wikis, you don't give up copyrights and you control who can access and edit each individual profile page. This enables families to privately share memories, photos, and sensitive information. But the profiles still exist on an interconnected worldwide family tree, so you get the benefits of collaborating with distant relatives and connecting your research with that of others. 100% free.
