Professional Genealogists use the Genealogical Proof Standard while conducting their research projects. Following these guidelines ensures a quality result.

  1. Reasonably exhaustive research has been conducted.
  2. Each statement of fact has a complete and accurate source citation.
  3. The evidence is reliable and has been skillfully correlated and interpreted.
  4. Any contradictory evidence has been resolved.
  5. The conclusion has been soundly reasoned and coherently written.

Any proof statement is subject to re-evaluation when new evidence arises.
