Here is the complete list of web sites used by FamilySearch (the genealogy initiative of the LDS Church), as of September 2010. FamilySearch has various sites that are accessible individually:
http://familysearch.org - FamilySearch is the official family history site of the Church of Jesus Christ of Latter-day Saints.
