Social networking for genealogy most often refers to the ability to build, share, and interact with online family trees. However, the breadth or depth of the online tools vary across the board. Some tools also offer other features of social networking such as sharing photos or creating calendars and timelines. The links in this section represent a variety of these types of sites.

TreeX.com - Genealogy, Family Trees, Records and online Family Tree builder
Relatives, friends or professional genealogists can work together or alone to help grow their family trees. Keep track of family ancestry and post photographs and historical text. The owner of the family tree can invite as many people as he wants to assist him in this effort. Trees are grown by inputting data directly to the site or by accessing computer files saved in the required GEDCOM format. Other information, photos and videos can also be inserted into the tree generically or for each member, improving quality and scope of the tree. A family tree can be kept confidential, set to public view or set to allow specified persons or relatives to access it -- and forums and user message boards have also been made available to make the exchange of information easier.
