Family historians are often reluctant to make full use of artificial intelligence, commonly referred to as AI, because of concerns regarding data accuracy, ethical implications and the potential loss of the human investigative aspect of research. Most of these concerns emanate from a lack of knowledge about AI which has been around for some time but is a “new” concept to many in family history research. However, we have been subject to artificial intelligence in our online research endeavours perhaps without realising it. AI as a technology is moving forward very rapidly so all family historians will be using it, perhaps without realising it.

Clearly AI is a topic that causes both interest and concern. When used responsibly and ethically, AI can have a huge impact on making records and family information more accessible. The algorithm technology is already affecting the genealogy community.

While recognising AI’s potential to accelerate tasks like transcription, many researchers fear it will introduce fabricated or incorrect information into carefully researched family trees; this is commonly referred to as hallucinations or fabricated information. AI tools, such as ChatGPT, are prone to creating false information with high confidence, including the worst case scenario of inventing ancestors, dates, and sources. This hallucination problem makes AI unreliable for establishing genealogical facts which will never replace personal research.

How useful is artificial intelligence?

AI often struggles with ambiguous or common names which can lead to incorrect links between individuals. It also lacks the human ability to interpret historical context, however complex, including naming conventions and patterns, societal normality or migration patterns, which, as we all know are crucial for accurate research. While the science behind artificial intelligence might seem complicated, understanding how AI can help in genealogy is not. This technological innovation can be quite helpful in your family history search and in learning about your family.

Using AI involves inputting personal data which raises risks regarding the privacy of living relatives and the ethical handling of data. There are also concerns about AI-powered image editing altering historical photos, thus distorting the historical record.

Many genealogists enjoy the process of discovery, detective work and the emotional connection to their ancestors which they feel is diminished by automation.

There is a fear that AI’s tendency to create polished narratives might override the necessary, careful analysis of primary sources, leading to a "hollowing out" of historical accuracy.

At the end of the day AI is not a replacement for the genealogists researching skills; it is only an assistant and a finding aid and should be treated as such.

How can AI assist or hinder

AI can help transcribe records and images including those which are difficult to read. It can extract text from historical documents, such as census records, birth certificates, wills, and newspapers, making them searchable and easier to analyse because it uses optical character recognition. Although AI can transcribe handwritten documents using OCR technology, documents with faded ink, unusual handwriting styles or damaged text could result in inaccuracies. Generally, however, it is pretty good at what it does.

AI can help with transcribing handwritten documents including letters, diaries or records which are difficult to read unless you have palaeographic skills. Many foreign genealogical records are compiled using the language of the country of origin. AI translation tools can make the interpretation of such records easier. This aspect has been around for years.

AI can help identify patterns in names, dates and locations that genealogists might have overlooked. It can help link family members across different documents or even suggest possible relationships. AI is almost useless when working with patronymics.

AI can be a great help in automatically finding relevant records by analysing an existing family tree and thus reduce the time spent manually searching through databases. The tools can suggest records based on matching name variations, misspellings, and changes in geographic locations, thus increasing the chances of finding elusive ancestors.

AI can only work using available data, so it is limited by missing or incomplete records or where records are damaged or never existed. If records have not been digitised, AI cannot access the information as most original records held in local archives will not be available for AI tools to function. There is still a need to undertake archive research to establish a full picture.

AI can analyse DNA results to suggest potential relationships between individuals, which can potentially help family historians resolve research challenges and even brick walls. It can group your DNA matches using shared segments, thus making it easier for family historians to identify common ancestors more quickly.

Perhaps one of the most dangerous aspects of AI is analysing data from records to automatically build family trees, supposedly allowing genealogists to build family trees faster. This will present problems which will need a significant amount of work to correct. However, AI can highlight inconsistencies in dates, places and relationships in a family tree, helping genealogists correct mistakes, so it is not all bad.

AI can be a great tool in the restoration of old photographs by improving their quality, removing blemishes and adding colour to black-and-white images. It can also compare faces in old family photos to identify family members where the origin of a photograph is not known or even across generations.

One very useful aspect of AI is that it can provide new suggestions based on collaborative research where others who have worked on common family lines, allowing potential connections that family historians were not aware of or had considered. AI virtual assistance tools can suggest relevant resources to researchers or even suggest records available on various genealogy websites.

AI is a great tool for providing historical insights; it can help place your ancestors in their contemporary environment and even identify social conditions and migration patterns. In any case, AI relies on the accuracy of historical records. If these records are incorrect because of transcription errors, personal interpretation or deliberate falsification, it will make incorrect connections.

By semi-automating mundane research tasks and undertaking electronic analysis, AI allows family historians to focus on strategic research but beware that AI can easily misinterpret or incorrectly match records due to incomplete data.

AI cannot apply reasoning, intuition or judgment to its findings so circumstantial evidence, family stories and direct local knowledge cannot be conceived by AI. It does not understand the emotional connections such as the importance of a particular ancestor to a family story because it only processes data based on information; it cannot "tell the story". At the end of the day AI-generated information still requires human verification and cannot be relied on to make final decisions, especially when records conflict or when historical context is needed to interpret data correctly.

Although AI is a powerful tool in genealogical research, it only works when combined with your human expertise and interpretation.

Things to be aware of when using AI

Understand copyright restrictions. When you use AI, check how you can use the information it provides. Normally there is no problem for personal use.

Protect your privacy. AI uses information it is given to improve algorithms or generate content for other users. This can pose a privacy risk, depending on how that tool uses the information. If you put information into AI, you need to check the settings options and privacy policies.

AI does not always list the sources of their information, but this is improving amongst the AI technology providers.

What AI produces is only as good as the information it has available. Summaries of information only include that which was available to summarise. AI does not think for itself, has no morals nor a perfect grasp of language.

As technology advances, so does the world of genealogy. This article just touches on the basics of how artificial intelligence can help you discover more about your ancestors.

Don’t shy away from AI. It is here to stay and can be a useful tool for anyone researching their family history. But do be careful!

For online data providers AI is continually improving so things will hopefully get better in the future.
