Did AI Hallucinate “65 Tons of Cargo”?
Yesterday I shared my response to Randy Seaver’s Saturday Night Genealogy Fun challenge, which invited participants to use Google Gemini 3 to describe an ancestor’s experience.
For my example, I selected my second great-granduncle, James H. Crawford, who migrated from Warren County, Indiana, to Dodge City, Kansas, in 1878. I chose this event for two reasons:
- He was the first Crawford family member to make the move west.
- His brother — my second great-grandfather — followed seven years later.
- Most importantly, I have contemporary newspaper articles describing the migration.
After posting the AI-generated narrative, a reader asked an excellent question:
Did the AI tool make up the reference to “65 tons of cargo”?
At first glance, that number does sound extreme. Sixty-five tons of goods seems like an astonishing amount for a single family relocating from Indiana to Kansas. It is entirely reasonable to wonder whether AI was “hallucinating.”
In this case, however, the figure came directly from a contemporary newspaper account — not from the AI’s imagination.
What AI did blur slightly was context.
The original article was describing a group of emigrants traveling together — not just the Crawford family alone.
Below are excerpts from the relevant newspaper articles.
From West Lebanon, Indiana (1878)
“…loading the cars with their household goods, dogs, chickens, birds, hogs, hay, corn, potatoes, flour, wheat, harrows, stoves, wagons, drills, plows, boxes, barrels, fruit cans, horses, mules, and cows, making altogether about sixty-five tons in seven freight cars…”
The article goes on to list the families emigrating, including:
- James H. Crawford
- J. M. Fleming
- R. P. Adams
- Mart. Etnire
- Charley Dickerson
- Rankins and Briggs
- And several single men
This clearly describes a coordinated migration effort, not one household’s belongings.
Arrival in Dodge City
Two Kansas newspapers further confirm the group arrival:
The Globe-Republican (5 March 1878) lists multiple families, including:
“J. H. Crawford, wife and six children…”
It also notes:
“They brought with them about twenty-five horses and mules, farming implements and household furniture.”
Similarly, the Dodge City Times (9 March 1878) reported:
“They brought most of their household goods and farming implements with them…”
What This Teaches Us About AI and Genealogy
This exchange highlights something important:
- AI did not invent the “65 tons” figure.
- The number was present in the source material I provided.
- However, AI summarized the migration in a way that could be interpreted as applying that entire quantity to the Crawford family alone.
This is not fabrication — it is compression.
And compression can blur nuance.
As genealogists, we are trained to:
- Check original sources
- Understand context
- Distinguish between individual and group events
- Cite carefully
AI can help us visualize and narrate historical experiences — but it does not replace our responsibility to interpret the evidence correctly.
In this case, the “65 tons of cargo” was historically documented. But careful reading reminds us that those seven freight cars carried the combined goods of multiple families beginning new lives on the Kansas prairie.
And that, perhaps, is even more impressive than one family alone.
