More Reflections on Doing Genealogical Research with AI Assistance

 

Comment on this AI generated image: I realize that a substantial number of people use their laptop as their main computer, but many of us also have more than one monitor, a tangle of cables to various hard drives and peripherals, and other random items on our work desks including, but not limited to headphones, mics, random papers, cough drops, and boxes of tissues. So, this picture is far from reality. 

A comment to my last post on Facebook got me thinking. Progress with any type of research depends heavily on your own ability to do the research. When I first started looking for answers to my questions as a nine- or ten-year-old child, my "research" was limited to the card catalog at the Phoenix, Arizona public library. I soon learned not only how to find what I was interested in while using the card catalog, but what was missing from the library's collections. My involvement with research and libraries continued with my university experience as a Bibliographer at the J. Willard Marriott Library on the campus of the University of Utah. Both my studies and my job required constant research. My initial experience with computers began with learning how to code a Shoshone/English, English/Shoshone dictionary onto the mainframe computer also on campus. Here I am many years later still doing exactly what I learned to do starting as a young child. 

By the time I started my current genealogical research, now 44 years ago, I was already doing legal research as a trial attorney and had access to the Phoenix law libraries, the library at Arizona State University, and my own collection of books. I also, immediately upon their introduction, began using the various home computers beginning with a TRS 80. As the internet came along, it merely expanded my research interests. 

Fundamentally, to do research on a computer connected to the internet, you still need to know how (and also why) to do basic research. When all this AI started showing up online, I immediately realized that you not only have to know how to interact with the AI Chatbot (Gemini) but you have to understand the responses. Research is research whether you are seeking information from a book somewhere in a large library or from a chatbot on the internet. To put the concept of research into the most simple terms available, it is this: you have to ask a question and then go find the answer. Now with the internet and with some assistance from various chatbots, I will have more questions and even more answers.

Now a comment on the technology. I will use whatever technology appears to be the best at answering my questions. Today, that appears to be Google's Gemini and NotebookLM combination. But that may change tomorrow or even later on today. I use the same tests I used in the libraries long ago. I looked for something I knew existed to test whether the library or whatever had the information. 

Today, to test the AI responses, I use examples that I have been using for the past 44 years; my Great-grandfather Henry Martin Tanner and my most remote Tanner relative, William Tanner. In both these cases, I do some preliminary research using the Full-text search capabilities of FamilySearch for finding the initial "new" to me documents. I already know the questions to ask and what to expect if anything works. I have been using both these test subjects for years for evaluating search engines like Google and web browsers such as Chrome, Safari, FireFox and etc. The key here is that AI research is sort of like working with a mirror of your own research abilities. You only get back what you can add and ask. Otherwise, it is the same things I would normally be doing for research that I have learned over my lifetime. I realize this isn't a very comfortable response, but you do have to come to the table with your own skills before you can make much progress. AI mainly accelerates the process and gives you more to work with than you ever believed possible. But, it doesn't answer all the questions. You have to do the research work first and last. 

Finally, for this post at least, you need to realize the vast amount of knowledge that the internet and the computers do not have "digitized" for consumption. This includes the vast amount of information in libraries and archives that is yet to be digitized. Watching the growth of online research opportunities is like watching a giant backhoe tear down a building, there is a lot of noise and it is fun to watch, but the real work doesn't begin until the new building is designed and built and meanwhile you have a lot of garbage to plow through to get to the answers.

Reflections on AI: Revising my opinions about doing genealogical research with AI


Beginning in December 2025, I became aware of the features of NotebookLM with my Gemini Pro account. Since then, I have worked on some extensive research projects using both Gemini 3 and NotebookLM. My main goal over the past 3+ years in consistently working with AI was to determine if a chatbot could do serious genealogical research. See Real Genealogical Research from FamilySearch Full-Text Search, Google Gemini and NotebookLM

Coupled with the FamilySearch.org Full-text search, NotebookLM and Gemini 3, it is now clear that this combination can assist in doing fully source-based genealogy as long as the genealogist using these tools has the knowledge and experience to evaluate the documents independent of any preliminary conclusions developed by the AI tools. However, in situations such as researching a remote ancestor with previously unavailable historical records, the ability of the tools to find and organize new information is invaluable. 

I would strongly suggest that such difficult research efforts will be aided my learning and using these specific tools.

The Genealogist’s Secret Weapon: Why "Domain Knowledge" is the Antidote to AI Hallucinations


Not long ago, I found myself staring at a record review generated by a cutting-edge AI. It was fast, it was clean, and at first glance, it was impressive. But as I looked closer, I felt that familiar "genealogical itch"—the one that tells you something is fundamentally wrong even when the data looks right.

The AI had linked a family in 1700s Maryland to one set of records. To the AI, it was a logical match of the places, names and ages. To me, the dates and specific geographic movements were historically impossible.

In the tech world, they have a term for what saved me from that error: Domain Knowledge.

The Generalist vs. The Specialist

We often treat AI like a specialized researcher, but in reality, it is a "Generalist." It has "read" the entire internet, but it hasn't lived in the archives. It understands the probability of words, but it doesn't understand the "ground truth" of a specific time or place.

This is where the concept of the "Human-in-the-loop" becomes more than just a catchphrase. In our research, the AI is the engine, but we are the steering wheel. The AI can process a thousand deeds in the time it takes us to read one document, but it may not know that a "Third Great-Uncle" mentioned in a Southern will might actually be a cousin, or that a "natural" son carries a very specific legal weight.

The Integrity Filter

As we move toward RootsTech 2026, the term "hallucination" is becoming part of our daily vocabulary. We’ve all seen it—the AI confidently "invents" a parent or a birthdate to fill a gap in the logic.

This is where your years of experience become an Integrity Filter.

Your domain knowledge is the mental database of naming patterns, migration trails, and local laws that the AI simply cannot replicate. When the AI suggests a match, your domain knowledge asks: Was that road open in 1830? Would a widow have had the right to sell that land under the laws of that specific state? If the answer is no, the AI’s "discovery" belongs in the trash, not your tree.

Building Your "Domain" for the Future

If the AI is going to handle the "heavy lifting" of transcription and sorting, our job description is changing. We are being promoted from data gatherers to Architects of Context. To do this well, we have to intentionally build our "Domains":

  • The Legal Domain: We must understand the dower rights and inheritance laws that governed our ancestors' lives.

  • The Geographic Domain: We need to know the "Great Wagon Road" as well as we know our own neighborhood.

  • The Technological Domain: We must learn how to "feed" our expertise into the AI, prompting it with the very context it lacks.

Moving Forward, Together

The theme for RootsTech 2026 is "Together," and I believe that applies to more than just our human kin. It represents the bridge between the machine's speed and the human's wisdom.

We aren't being replaced; we are being called to a higher standard of accuracy. When we bring our hard-earned domain knowledge to the table, we ensure that the stories we tell consistent with historical records. 

The "Aha!" Moment: A Case Study in Domain Knowledge

If you want to see another example of the difference between AI logic and human expertise, look no further than the "Same Name" trap.

In a recent research session, I asked an AI to analyze a specific family line. The AI confidently merged two different families because both fathers shared the same name. On the surface, the dates were "close enough" for a machine that thinks in probabilities.

But as a seasoned researcher, I saw the flaw immediately:

  1. The Geography: The families lived in two distinct regions with no documented migration trail between them.

  2. The Chronology: The birth dates of the children overlapped in a way that defied biological reality.

        Issues such as this one can be addressed by two rules or methodologies.

  • The "Trust but Verify" Rule: Never accept an AI's "Match" without running it through your own geographic and chronological filters.

  • The "Correction Loop": Use your domain knowledge to find an error, but don't give up on the tool. Instead, you should "teach" the AI by providing the specific domain knowledge it missed (e.g., "These are two different men because the 1850 census shows them in different states simultaneously").

When we correct an AI chatbot, we aren't just fixing a mistake in our tree; we are practicing the exact type of critical thinking that defines a master genealogist. We are proving that while the machine can find the data, only the human can find the truth."
