AI Hallucination and Verification

Understanding AI hallucination is critical for responsible genealogy research. AI hallucination occurs when artificial intelligence generates plausible-sounding but false information. In genealogy, this might mean inventing records, ancestors, or historical facts that do not exist.

Common AI Hallucinations in Genealogy

Genealogists should watch for these specific hallucination patterns:

Fictitious Records: AI may cite census records, marriage certificates, or military documents that sound authentic but never existed. Always verify record citations against actual databases.
Invented Sources: When asked for bibliography entries, AI sometimes creates plausible-sounding books or articles that were never published. Check every source before including it in your research.
Confused Identities: AI may conflate two people with similar names into one biography, merging details from different individuals. Cross-reference every fact across multiple records.
Anachronistic Details: AI might place historical events in wrong time periods or attribute modern concepts to earlier eras. Verify historical context independently.
Fabricated Family Connections: When analyzing possible relationships, AI may confidently assert connections without sufficient evidence. Treat AI relationship suggestions as hypotheses requiring verification.

Verification Best Practices

Protect your research integrity with these verification habits:

Primary Source Rule: Never add information to your tree solely based on AI suggestions. Locate the actual record image or document.
Multiple Source Confirmation: For every significant fact, seek at least two independent sources. Birth dates should appear on birth certificates, census records, and possibly death certificates or tombstones.
Chain Verification: When AI suggests a parent-child relationship, verify the connection through birth records naming parents, census records showing household composition, and wills or probate records listing heirs.
Source Citation Standards: When using AI-generated content, clearly distinguish between AI assistance and verified facts in your notes. Never cite AI as a primary source.

Source Citation for AI-Assisted Genealogy

Proper source citation remains fundamental to quality genealogy research, even when using AI tools. Understanding how to document AI assistance maintains your work’s credibility and helps other researchers evaluate your conclusions.

How to Cite AI-Generated Content

When AI helps generate text, ideas, or analysis for your genealogy project, acknowledge its role appropriately:

For AI-Assisted Writing: In your methodology notes or acknowledgments, state which AI tool assisted with drafting and that all facts were independently verified. Example: “Draft biographical narrative developed with ChatGPT assistance, all facts verified against primary sources.”
For AI-Generated Transcriptions: When using AI transcription tools like Transkribus, cite both the original document and the transcription method. Example: “Transcription generated using Transkribus AI handwriting recognition, verified against original microfilm.”
For AI Research Suggestions: When AI suggests a research path that proves valuable, document the suggestion source in your research log, then cite the actual records you found.
Never Cite AI as Evidence: AI output itself is not evidence. Always trace claims back to primary sources and cite those documents directly.

Citation Format Examples

When documenting AI tool usage in your research notes:

Research assistance: Claude (Anthropic) used for document analysis of 1850 census enumeration. All extracted data verified against Ancestry.com record image. Analysis completed July 2026.

For AI-transcribed documents:

Will of John Smith, Greene County, Ohio, probate file 1847. AI transcription via Transkribus (model: English Handwriting 19th Century). Transcription verified by comparison with original document at Ohio Historical Society.
