Evidence Analysis for Genealogists – NGS Review Part 2

The first class after visiting the exhibit hall was titled "Prove It! Evidence Analysis for Genealogists" by Laura Murphy DeGrazia, CG. One thing I have been wanting to learn more about is citing sources and evaluating evidence. Laura did a great job in her presentation.
  • Waiting for the first class to start. "Prove It! Evidence Analysis for Genealogists"
  • Source - Original: earliest form Derivative: copied from the original
  • There is no gaurantee the original source is correct...
  • "No single source is enough." Always get as mush as possible.
  • A source can include both primary and secondary. Take a death certificate for instance.
  • Why did our ancestors lie about dates, places, names, etc. on records?
  • Two types of evidence - direct or indirect. Direct: answer a question on it's own, Indirect: must be combined with other evidence
  • Use the Genealogical Proof Standard GPS to prove evidence.
  • To learn more about the GPS, go to the ThinkGenealogy blog by @marktucker (
  • Laura is giving examples of analysis on her own family-there are spelling errors along with dates. Always do more research
  • Settling for a derivative source when there are originals may cause you to lose valuable information and be misinformed.
