Lineage
The research engine

The librarian who never sleeps.

Every family extraction triggers a research run. Eight archives, queried in parallel, for every person, place, and event we've identified. Findings are filed and proposed as candidate facts for your review — never silently merged.

  1. FamilySearch
    Free
    When we query it
    Every person, every couple
    6B+ records: vital, census, immigration, church. We hit Person Search, Places, Date Authority, and Person Matches against each individual in your extraction.
  2. NARA Catalog
    Free
    When we query it
    Every person with US presence
    US Census 1790–1950, military service records, naturalization paperwork, ship manifests, draft cards. Single most powerful free archive for US ancestors.
  3. Chronicling America (Library of Congress)
    Free
    When we query it
    Every birth/death in US 1789–1963
    Searches digitized US newspapers for obituaries, wedding notices, accidents, business openings. Returns full page images with OCR text.
  4. GeoNames
    Free (with attribution)
    When we query it
    Every unresolved historical place
    Resolves 'Czaraholand, Germany' against modern atlases. Returns coordinates, alternate spellings, and country boundary changes over time.
  5. BillionGraves
    Free tier
    When we query it
    Every death event with known burial
    Cemetery photographs and headstone transcriptions, GPS-tagged by volunteer photographers. Often the only photograph that exists of a grave.
  6. HathiTrust
    Free
    When we query it
    Place + surname deep dives
    Out-of-copyright county histories and published genealogies. Where the 1903 Elkhart County History entry on August Lorenz might live.
  7. Internet Archive
    Free
    When we query it
    Place + surname, broad search
    Books, photographs, regional newspapers, ephemera. The catch-all for anything that doesn't fit cleanly elsewhere.
  8. WikiTree
    Free
    When we query it
    Every person, cross-reference
    Collaborative 30M+ profile global tree. Often the fastest way to find that a third cousin has already done the work on a shared ancestor.
How findings make it to your site

We never silently rewrite your data.

Every finding is staged as a candidate_fact in your research queue. You see what the archive said, the evidence behind it, how confident we are, and a one-click button to accept, reject, or send back to the family for verification.

Conflicts (Aunt Carrie said 1889, Jim's memoir says 1884) are preserved as conflicts. You decide which to publish, or both.
