Genealogical Proof Standard

The Genealogical Proof Standard was designed as a guide for proof in genealogical research. The five components to the Genealogical Proof Standard are: [1]

1. Reasonably exhaustive research

2. Complete and accurate source citations

3. Tests through analysis and correlation

4. Resolution of conflicting evidence

5. Soundly reasoned, coherently written conclusion

New evidence will necessitate the re-evaluation of a proof.
