 Frequently Asked Questions

Iowa Genealogy Search, FAQ

Is the 1950 census released?

Yes. Under the 72-year rule, the 1950 U.S. Census was released by NARA on April 1, 2022 and is free to search on archives.gov and familysearch.org.

How do I request a military service record?

NARA's National Personnel Records Center (NPRC) in St. Louis holds military service records. Requests use SF-180 and are free for the veteran or next of kin.

Do I need a paid subscription to do genealogy?

No. FamilySearch, Archives.gov, the Library of Congress, and most state archives provide substantial free access. Commercial services (Ancestry, MyHeritage) add convenience and private trees but not exclusive records.

Where are vital records for the 1800s kept?

Before state-level vital registration (roughly 1890, 1920 depending on state), most births, deaths, and marriages were recorded only by the county, the church, or the family Bible. State archives and FamilySearch are the primary starting points for that era.
