Three records. Three completely different birthplace answers. A German Lutheran church register from Schuylkill County, Pennsylvania says New York. The 1880 US Federal Census says Germany. A Pennsylvania death certificate says Pennsylvania. All three claim to document the same German immigrant ancestor. Not one of them agrees.

In this episode of Ancestors and Algorithms, Brian walks through a step-by-step AI-powered workflow for resolving conflicting genealogical evidence, using a German immigrant ancestor from the Rhine Province of Prussia who arrived through New York in the 1860s and spent the rest of his life in Pennsylvania's coal region. This is Episode 35 and Part 2 of the GPS Mini-Series, with a full-episode focus on GPS Element 4: the resolution of conflicting evidence.

Three AI tools are demonstrated with exact copy-paste ready prompts you can apply to your own conflicting records today. Perplexity with Comet Browser researches historical context for German immigrant Lutheran church records and documented immigrant identity patterns. Claude performs systematic document comparison and evaluates which informant knew what, and when. ChatGPT brainstorms every ranked explanation for why an ancestor might tell his own pastor a different birthplace than he gave the census enumerator five years later.

What you will learn in this episode:

• Why death certificates are the least reliable source for immigrant birthplace information, and what the research literature says about why
• How 19th-century German Lutheran Kirchenbucher in Pennsylvania captured birthplace information and how immigrant identity shaped the answers given
• The critical difference between explaining a conflicting record away and actually resolving it to a defensible professional standard
• How all five elements of the Genealogical Proof Standard work together when your evidence fights itself
• A three-step AI framework applicable to any conflicting records problem in any era and any country

If you research German ancestors, Pennsylvania family history, 19th-century immigration records, or any ancestor whose census records, church records, and death certificate simply do not agree, this episode gives you the exact prompts and a repeatable framework you can use today.

Tools demonstrated: Claude (claude.ai), Perplexity with Comet Browser (perplexity.ai), ChatGPT (chat.openai.com). All free tiers.

Australian and UK listeners: this conflict resolution framework applies directly to convict transportation records, colonial census data, Scottish parish registers, and General Register Office civil registration. Same approach, different archives.
