RESEARCH WITH CONFIDENCE
Good genealogy is more than finding a name that fits. Learn how to evaluate evidence, document your sources, and build conclusions you can defend.
THE GENEALOGICAL PROOF STANDARD
Without careful research, a family tree can quickly become more fiction than family history. The Genealogical Proof Standard provides a framework for building conclusions supported by reliable evidence.

About the Genealogical Proof Standard
The Genealogical Proof Standard was developed by the Board for Certification of Genealogists (BCG) to provide a consistent method for evaluating genealogical evidence and reaching sound conclusions. It consists of five elements that guide careful research, documentation, analysis, conflict resolution, and written conclusions.

Our explanations summarize the five elements in our own words.
Conduct Reasonably Exhaustive Research
Search broadly enough to reduce the chance that an important record or piece of evidence has been missed. Remember that more than one person with the same name may have lived in the same place at the same time.
Analyze & Correlate the Evidence
Compare information from multiple sources and determine whether it relates to the correct person, family, place, and event.
Cite Your Sources
Record enough information so you and other researchers can find the source again and understand what evidence it provides.
Resolve Conflicting Evidence
Conflicting information is common in genealogy. Identify the conflict, investigate it, and explain how you reached your conclusion.
Write a Clear Conclusion
Explain how the evidence supports the relationship or conclusion you reached. Good genealogy should allow another researcher to understand how you got there.
