Guide 01

Search OCR, verify the scan

Use OCR to locate names, places, dates, and phrases. Then inspect the PDF image before quoting or relying on the result; columns and proper names are common OCR failure points.

Guide 02

Separate source from interpretation

A newspaper notice, census schedule, deed, compiled genealogy, and modern lineage chart do not carry the same evidentiary weight. Record what the source itself says before adding interpretation.

Guide 03

Verify one generation at a time

For a parent-child link, look for converging evidence such as wills, probate files, marriage records, census households, deeds, family Bibles, cemetery records, and contemporary notices.

Guide 04

Search variants and OCR errors

Try initials, married names, alternate spellings, phonetic variants, and common OCR substitutions. Search uncommon surnames or place names before adding broad terms.

Guide 05

Cite the archive and the original source

Cite the archive record URL for access, but preserve the original publication or repository details whenever they are visible in the scan.

Guide 06

Treat family tradition as a lead

Family tradition can preserve useful clues, but label it as tradition until documentary evidence supports the claim. The revised Poston genealogy is a model for explaining and correcting inherited traditions.

Recommended research sequence

Start with the surname and record search, open the source PDF, record the original citation, compare the OCR against the scan, and then test the fact against independent records. For family relationships, avoid jumping across generations because names repeat frequently.
