Missouri Descendancy Research

Step 1. Find descendants in every possible census record, 1850-1950, online.
Census records, widely indexed, are a fast way to identify members of families, their approximate year of birth, and the state where they were born. That information hints where to look for birth, marriage, and death records for more detailed information. One disadvantage is they are 10 years apart. Children born and dying within that 10-year span can be overlooked.

For more information on census records, see Missouri Census and United States Census.

Step 2: Find birth, marriage, and death records online.
Government records, known as civil registration or vital records, were kept in Missouri statewide beginning in 1909, although counties may have kept earlier records. They provide full dates and places. They are sometimes indexed, and can be searched by child or parent names. They are especially useful because they name other family members, For example, marriage records name the parents of the bride and groom. Death records are especially helpful because they name parents, who lived years earlier, even before other records were kept. Coverage in the earlier years can be incomplete however. In some states, church records were gathered to provide earlier certificates.
