Sources, Information & Evidence in Pictures - MGP2 Study Group 2 Chapter 2

This post is part of DearMyrtle's Hangout on Air series, MGP2 Study Group 2, studying Mastering Genealogical Proof by Thomas W. Jones.¹ Hangouts are every Sunday morning at 10:00 AM Eastern US time. Join us to learn more about the discipline of genealogical work and how adhering to its standards will improve your family history results. Your family will thank you.

  1. Love the graphics, Jennifer. What an effective way to visualize the differences between types of sources, information, and evidence. Well done!

  2. Well done and very clear. I am sure the creation of the infographics really reinforced the differences in these different concepts for you.
