There are differences, however. But we genealogists do not have judges to tell us what can or cannot be heard. We look at every shred of information we find and sometimes draw incorrect conclusions because we do not know how to weigh it or how to resolve the frequent occurrence of conflicting evidence. Researchers often assume that if several pieces of information agree, the data must be correct. Such assumptions often lead to erroneous pedigrees and frequently create genealogical dead-ends.
Evidence is the physical form in which information is presented to the senses.
Proof is a name for a process that takes place in the mind, not for the evidence on which it is based. However, the term is also used to refer to the documents utilized as evidence for many lineage-society applications. The compiler may or may not have overridden default options or included footnotes to indicate variants. Remember to cite the specific sources you actually used in compiling your family history. Secondary evidence or source.
