If you are at all interested in an online family tree program that promotes careful research and extensive documentation, you should be familiar with WeRelate.org. Quoting from the website, "WeRelate is a free public-service wiki for genealogy sponsored by the Foundation for On-Line Genealogy in partnership with the Allen County Public Library. It is the world's largest genealogy wiki with pages for over 2,548,000 people and growing." I have long considered WeRelate.org to be one of the most important and viable alternatives to almost all of the other online family trees.
Now, WeRelate.org has teamed with Find-A-Record to provide links from each individual in the wiki to that geographically centered record finding website. Here is a screen shot of an individual page in the WeRelate.com database with an arrow indicating the link to Find-A-Record.
Here is a screenshot of part of the resultant list of records from Find-A-Record:
This is a major step for a program such as WeRelate.org because now it is essentially directly connected to searches in both FamilySearch.org's Historical Record Collections and Ancestry.com. Maybe this is a reason to look at both programs more closely.
