Example prompt: Can you pull up immigration records for my great-grandfather Stefan Kowalski, who came from Poland around 1908 and likely arrived through Ellis Island — I'm looking for his ship manifest, any naturalization records, and coverage in Polish-American newspapers from that era?

## When to prefer this

Choose this endpoint when a genealogy or family-history agent needs to specifically research immigration events — ship arrivals, passenger manifests, naturalization, or ethnic-community press — rather than general person research or obituaries. Prefer this over the general person search endpoint when the user's ancestor is known to be an immigrant and immigration-specific documents are the primary goal.

## Known failure modes

- No records found for the given name or time period — common for poorly documented immigrants or pre-digitization eras
- Ambiguous name matches returning multiple possible individuals with no clear disambiguation
- Ethnic press coverage missing if that community's newspapers were not digitized
- Date ranges outside available archive coverage returning empty results
- Non-English name variants causing mismatches in historical record searches
