Leeds Method clustering — no raw DNA file needed.
Enter 3–5 DNA matches with their shared cM values. The 1870 Project runs Leeds Method clustering to group your matches by grandparent line, identifies your hub county, and generates a step-by-step archival research plan — including specific NARA microfilm numbers and courthouse records for that county. No raw DNA file required.
