Record ladder
Search the period, not today’s interface.

2
Household and community
Use censuses, tax lists, directories or neighbors when the period supports them.
3
Event record
Target the record created by the event: land, probate, court, church, vital, military or immigration.
4
Context and cross-check
Use maps, newspapers and a second independent record to test identity.
