When initial searches return a candidate name, or when the clues strongly suggest a known historical figure and you can form a hypothesis before exhaustive searching.
When a candidate name emerges, immediately switch to targeted verification: search "[person name] [specific detail]" for each constraint. All must match.
If no candidate emerges, use cultural context (Japanese immigrants, American frontiersmen, Indian poets) to narrow the field, then verify when a candidate appears.
Checklist: (1) Time period. (2) Location. (3) Family details. (4) Events/achievements. (5) Remaining constraints.
[person name] [specific detail] [year]
[person name] children siblings "third child" family
