FamilySearch
I've probably linked to this website at least half a dozen times in past articles, so I thought it was time to do a write-up specifically on the FamilySearch Website.
There are many resources at this website including:
1. Printable Pedigree Charts and Family Group Records (Not really necessary if you store all your names in a computer file, but some people still like to have a hard copy of their information)
2. Free genealogy software that is easy to download called Personal Ancestral File (The PAF program I'm constantly referring to and the program you need to use if you are LDS and want to do temple work)
3. Search for Ancestors (When you type in a name and search for it on this site, FamilySearch will search in the Ancestral File, the Pedigree Resource File, the US Social Security Index, the International Genealogical Index, and the 1880 US Census as well as the 1881 Canada Census.
4. Email groups who are researching the same names (I just realized they had this feature, so I haven't tried it out yet -- I have signed up though and hope to find some contacts with new information)
5. Surname Search (This is especially useful for finding written family histories)
6. Family History Center locations
7. Links to other Family History Websites
Family Search was ranked the 2nd most popular website used by Professional Genealogists, probably because there is more free data here than anywhere else in genealogy. There are about a billion names in their database, so you're bound to find some new information.
