Aaron Holt, archives technician at the National Archives Fort Worth, said it is not unusual for genealogists today to have conflicting stories about an ancestor if oral history was not passed down in a deliberate way through the generations.
“I tell people all the time that it only takes three generations to lose a piece of oral family history,” Holt said. “It must be purposely and accurately repeated over and over again through the generations to be preserved for a genealogist today.”
If that piece of oral history is about an ancestor’s death, Holt said the chance of the truth being lost is even greater.
