Added some social networking sites for family historians today. Several of these sites are long established such as Ancestry's One World Tree, Rootsweb's WorldConnect, Genealogy.com's World Family Tree and GenCircles Global Tree. The next generation of tree-building websites go a step further. Onegreatfamily.com allows you to upload you GEDCOM and promises to link with the tree it holds. If submitters agree to merge data the tree can be viewed as a single expanded tree.

Using these sites and networking online has widened researchers chances of finding individuals that they are searching for. Search as many sites as you can as individuals listed within sites vary.
