Information, Genealogical

Genealogical information is potential evidence gleaned from a source, and may be either primary or secondary information depending upon the degree of participation (first hand knowledge) of the informant. Primary information comes from people who were participants, observers, or otherwise in a position to have first-hand knowledge of the recorded information. Secondary information comes from those who were not present at the events, and thus are furnishing hearsay or traditional information, or are quoting original or derived records.
