AI for Genealogy: Tracing Your Immigrant Ancestor with AI - Death Certificate to German Church Records

Ancestors and Algorithms: AI for Genealogy

What if you could trace your immigrant ancestor from their American death certificate all the way back to their exact birthplace in the old country—in just six hours? In this complete case study episode, I share exactly how I did it using four AI tools strategically.

This isn't theory. This is a real research journey I completed last week, tracing German immigrant Heinrich Mueller from his 1923 Pennsylvania death to his 1875 baptism in Stuttgart. I'm walking you through every tool I used, every prompt that worked, every mistake I made, and every document I found.

🔍 THE COMPLETE IMMIGRANT RESEARCH ROADMAP

Starting with just vague family stories of "somewhere in Germany," I built a complete paper trail:

• Pennsylvania death certificate → extracted key details with Claude AI
• Naturalization records → analyzed with ChatGPT for exact arrival information
• Ellis Island manifest → transcribed with Gemini's breakthrough handwriting recognition
• Hamburg departure records → decoded German columns with Perplexity
• German church records → tackled old German script (plus when you REALLY need Transkribus)

🎯 WHAT YOU'LL LEARN

This 45-minute deep dive shows you:

• Which AI tool to use for each document type (and why it matters)
• Word-for-word prompts you can copy for YOUR research
• How to verify AI results across multiple sources (genealogical proof standards)
• When "AI in a pinch" is good enough vs. when you need specialized tools
• Research planning strategies that save hours of random searching
• How to handle foreign language records and old handwriting
• International adaptations for UK, Australian, and other researchers

💡 WHY THIS EPISODE IS DIFFERENT

Unlike most genealogy podcasts that discuss techniques theoretically, I'm sharing my actual research notes. You'll hear about the failed prompts, the "aha!" moments, and the strategic decisions I made at each step. This is the complete methodology you can replicate for Italian, Irish, Polish, Chinese, Mexican, or any immigrant ancestor.

🌍 FOR INTERNATIONAL LISTENERS

Whether your ancestors came through Ellis Island, UK ports, or Australian immigration stations, this process works. I include specific adaptations for researchers outside the United States throughout the episode.
