EVIDENCE FOR PROOF Evidence is the means of proving or disproving a fact. There are five types of evidence: 1. PRIMARY: Primary evidence is that from a record when the record itself is the cause or result of the action or fact to be proved. Examples are: Vital records, Wills, Church Records, Tombstones etc., This is the best evidence. 2. COLLATERAL: Collateral evidence is when it is collateral to the purpose of the records but never the less an integral part of the record: Example: If a man speaks of his daughter by her married name, it signifies a marriage when no marriage record can be found. 3. SECONDARY: Evidence consists of statements made by persons of facts they know of their own knowledge: Examples: Oaths, Old Letters, Depositions. 4. CIRCUMSTANTIAL: If two or more facts are so related, that if one which can be proved by a higher type of evidence is true. When the other is necessarily, true. Example: Record shows a daughter of a man and later he marries someone, it shows he was married before and had at least one daughter. 5. REPORTED: Rumor, Hearsay, County Histories, and Many Biographies. These are the least trustworthy but good for clues. SOURCES OF GENEALOGICAL MATERIALS 1.
