About this webinar

Each U.S. state has a state archives to preserve government records from counties and state agencies. Did you know that some states have branches of the state archives? These are facilities found around the same state. Have you been missing some records that may fill in blank spots on the family tree? The reasons for their existence, ways of operating, collection finding aids, types of collections, and staff are varied. Learn more about these, access, staffing, and the often-surprising material and indexes they hold. The real life examples will convince you of what you may have missed!

Key points and insights

State archives are often overlooked goldmines for genealogists, housing vast collections that extend far beyond basic vital records. This webinar, featuring internationally recognized expert Paula Stuart-Warren, dives into the specialized branches of state archival systems—such as ARCs, IRADs, and ONAHRs. These regional depositories often hold unique local records, including business ledgers, school censuses, and coroner files, that haven't yet made it to major online databases. For any researcher who feels they have "tried everything," understanding how these regional networks function—and how to access their onsite and digitized treasures—is the key to breaking through long-standing brick walls.

  • Regional Networks Offer Localized Depth: Systems like the Illinois Regional Archives Depository (IRAD) and Wisconsin’s Area Research Centers (ARCs) were created to solve storage issues at state capitals, resulting in rich, county-specific collections (e.g., naturalization records, almshouse registers, and justice of the peace books) kept closer to their place of origin.
  • The Power of "Non-Traditional" Records: Beyond birth and death certificates, regional archives house fascinating artifacts like railroad payrolls, teacher permanent records, and morgue registers, which can provide specific details on an ancestor's occupation, physical description, and even family relationships.
  • Hybrid Access is Essential: While many archives now offer digital indexes and "full-text search" capabilities via partnerships with FamilySearch, much of the most valuable material remains in physical formats or older published guides; interacting with student interns and archivists via phone or email remains a vital research strategy.

To truly master the nuances of regional research and see these unique records in action, we highly encourage you to view the full webinar. Seeing the specific search strategies and visual examples of rare documents will give you a competitive edge in your genealogical pursuits.
