Everyone who's doing anything in genealogy and family history research really owes it to themselves to get to know the Mormons a bit better. The resources that they have available at FamilySearch, Ancestor Search, and at their academic arm, Brigham Young University, are a genealogist's best friend.
Of particular note are the online free genealogy courses at BYU.
Their free Family History course offerings include:
- Finding Your Ancestors
- Introduction to Family History Research
- Vital Records
- Military Records
- France: Vital Records (ditto for several other countries)
- Germany: Immigrant Origins (again, a ditto for elsewhere)
- Scandinavia: Jurisdictions, Gazetteers, and Maps
You get the idea. There's a lot here, both for general interest, as well as for specialty areas that might just help you burst through the brick wall on your own family's history.
A few courses are immediately accessible online, while others require a simple registration, which basically involves providing an email address.
These are wonderful offerings, and are absolutely free. Take advantage of them.
Don't forget to also check for your family history at Ancestry.com and NewspaperArchive. These are subscription databases, but they are among the most powerful research tools available for looking into family roots.
