Effective family history research requires some understanding of the historical events that affected your family and the records about them. Learning about wars, governments, laws, migrations, and religious trends can help you understand political boundaries, family movements, and settlement patterns.
State, county, and local histories often contain biographical sketches of local citizens, including important genealogical information. This may be one of the best sources of information for some families. See Arizona Genealogy and Arizona Archives and Libraries
County and local histories often contain biographical and historical information about residents and their families. They may provide the occupation, previous residences, birth date, or birthplace (city, county, and state or country).
Information about a family may be found in a history under the married name of a daughter or sister. Relatives or clues are often found by studying the pages that have biographies of residents or that tell the history of the town or township where an ancestor lived.
Histories are great sources of genealogical information. Many contain biographical information about individuals who lived in the area, including:

Some of the most valuable sources for family history research are local histories. Published histories of towns, counties, and states usually contain accounts of families. They describe the settlement of the area and the founding of churches, schools, and businesses. You can also find lists of pioneers, soldiers, and civil officials. Even if your ancestor is not listed, information on other relatives may be included that will provide important clues for locating your ancestor. A local history may also suggest other records to search. Local histories are extensively collected by the Family History Library, public and university libraries, and state and local historical societies. The United States Research "History" page cites nationwide bibliographies of local histories which include histories of Arizona.
- A bibliography that includes some local histories is Arizona Gathering II, 1950-1969: An Annotated Bibliography. 
State Histories Useful to Genealogists
Good genealogists strive to understand the life and times of their ancestors. In this sense, any history is useful. But certain kinds of state, county, and local histories, especially older histories published between 1845 and 1945, often include biographical sketches of prominent individuals. The sketches usually tend toward the laudatory, but may include some genealogical details. If these histories are indexed or alphabetical, check for an ancestor's name. Some examples for the State of Arizona are:
- History of Arizona. 
- Arizona: The History of a Frontier State 
- Robinson, William Henry. The Story of Arizona. Phoenix, Ariz: Berryhill Co, 1919. AccessGenealogy.com scan of the entire book.
