Discover how AI signature analysis solved a 120-year-old genealogy mystery involving identity theft, mining deaths, and desperate immigrants in Pennsylvania coal country. This complete tutorial demonstrates using free AI tools—Gemini, Claude, Perplexity, and ChatGPT—to analyze handwriting, compare documents, and uncover hidden family secrets.

THE MYSTERY: Two property deeds, same name, same land—but completely different signatures. One showed educated European penmanship, the other barely literate scrawl. Were these signed by the same person? AI revealed the shocking truth: identity substitution after a tragic mining death.

WHAT YOU'LL LEARN:

AI Signature Analysis: Use Gemini's free image analysis to objectively compare handwriting across documents. Get exact prompts for analyzing letter formation, pen pressure, and writing systems that distinguish one person from another.

Document Pattern Recognition: Learn Claude's powerful chronological analysis technique to spot identity transitions, witness changes, and gaps in the documentary record that reveal when someone assumed a new identity.

Historical Context Research: Master Perplexity's citation-backed research to understand why immigrants changed identities—mining accidents, unreported deaths, "paper sons," and substitute identities in early 1900s America.

Theory Generation: Use ChatGPT to systematically generate and evaluate multiple explanations for genealogical mysteries, avoiding tunnel vision and confirmation bias.

TECHNIQUES DEMONSTRATED: ✓ Free-tier AI tools only (Gemini, Claude, ChatGPT, Perplexity) ✓ Copy-paste ready prompts for immediate use ✓ Multi-tool workflow combining signature analysis, document comparison, and historical research ✓ Primary source verification methods ✓ Advanced genealogy proof standards with AI assistance

REAL GENEALOGY CASE STUDY: Follow the investigation of Jan Kowalski, Polish immigrant who purchased Pennsylvania farmland in 1897—then "sold" it in 1902 with a completely different signature. AI tools revealed coroner reports, mining accident records, and boarding house keeper documentation proving the original Jan died in 1901, and another immigrant assumed his identity to claim naturalization papers and property.
