The first record is a family data collection provided by Ancestry.com:
Thousands of families are known to be present in the database, containing 20 million names in 5 million records. This data covers the entire U.S. for a wide expanse of years. At a minimum, each record contains an individual's name, date and place of birth, and the name of his or her father. A complete record will contain the following information for an individual: Name, Date and Place of Birth, Date and Place Married, Date and Place of Death, Name of Spouse, Name of Father, Name of Mother, Use this database as a finding tool, just as you would any other secondary source. When you find the name of an ancestor listed, confirm the facts in original sources, such as birth, marriage, and death records, church records, census enumerations, and probate records for the place where the even took place.
