You rarely find a direct statement that 'John was the son of James,' but you can build an ironclad case through indirect chains: James's will names John as heir, John appears next to James on a property deed, and three different sources refer to them living in the same household. Mastering indirect evidence reasoning is the core skill of genealogical problem-solving.
Indirect evidence chains are sequences of related facts drawn from multiple records that collectively point toward a genealogical conclusion even though no single document states that conclusion directly. Researchers build these chains when direct records such as birth certificates do not exist or have not survived.
AI tools support indirect evidence chain building by helping researchers identify which document types are likely to contain supporting facts, by organizing extracted data points into logical sequences, and by prompting researchers to consider alternative explanations so that the final conclusion is as well-supported as possible.
