Leveraging all three together on a particular research question can become a powerful battering ram with which to attack your proverbial brick walls.
Ancestry is a subscription-based service providing digitized records, the world’s largest autosomal DNA testing database, and millions of user-created family trees. Leveraging all three together on a particular research question can become a powerful battering ram with which to attack your proverbial brick walls. Although viewing documents usually requires a subscription, Ancestry does offer an extensive free indexes collection (which has more than just indexes) and periodically provides access to record sets that are normally behind the pay wall. These tend to be theme-based events centered around a holiday weekend.
