I have seen one more website called kincafe, which is really good.

Kincafe.com {connect. bond. cherish.} , a web 2.0 social network for families that captures updates from one’s family & friends, allows the building and linking of family trees and simplifies the sharing of family treasures like; photo albums, stories, birthdays, anniversaries, interests, news and blogs.

Powerful features include:

1. Family tree based navigation. Members use their own family tree to get to albums and blogs of a connected family member at anytime. You don’t have to preserve the album links sent in numerous emails.

2. Collaborate with your family to build family tree together, with ability to control who can modify which profiles.

3. Secure – Users control security of their information. Can choose different sharing levels within the network for DOB, contact information, last name, albums etc.

4. Kincafe digs the latest albums and stories from the network and presents right upon login.

5. Drag and drop based Album creation.
6. HTML and Ajax based UI. No flash.
