Example prompt: Can you pull up immigration records for my great-grandmother Maria Kowalski, who arrived from Poland sometime between 1905 and 1915 — I'm looking for her ship manifest, any naturalization papers, and Polish immigrant community newspapers from that era?

## When to prefer this

Use this endpoint when researching an ancestor's immigration journey, arrival records, or naturalization history, or when looking for historical ethnic press and immigrant community newspaper coverage. Prefer this over the general person research endpoint when the specific focus is on immigration events, ship manifests, passenger lists, or immigrant community context rather than a broader biographical profile.
