Mastering Genealogical Proof – on Sale for 10% Off through Wednesday, Sept. 9, 2015

ngs21At one point in time or another, every genealogist faces questionable sources and must determine whether to accept or reject these sources as accurate. The question arises, “can we not determine reliably which findings reflect the past?” Then, of course, if we do decide a source is acceptable, or credible, how do we prove this to others?

These are the questions for which Thomas Jones attempts to provide answers in his new book, Mastering Genealogical Proof. Better stated, perhaps, is to say in Jones’ new textbook. For this book is written in textbook style. Each chapter provides the critical learning followed by problems, which provide the reader a opportunity to practice ans set in memory the concepts shared within the chapter.

In 2000, the Board for Certification of Genealogists developed and produced the “Genealogical Proof of Standard,” a.k.a. GPS. This standard was an attempt to create a system for proof, pulling from the field of law and applying the best practices used by genealogists. The final product was a fifty-six point research standard.

Jones’ textbook pulls from the GPS, distilling its contents into an understandable and useable methodology any researcher, student, or newbie genealogist can use. The book teaches and guides the reader with easy to read chapters containing sixty-two real world exercises. The examples were pulled from the author’s own family’s genealogy and contain American, British, Germanic, and Irish roots. These examples demonstrate the use of this methodology across “diverse ethnicities and geographic origins.”

In the author’s own words:

“I wrote this book to help other genealogists understand in a reasonable time frame what decades of trail-and-error have taught me. I hope the text and exercises will save them from the embarrassing blunders and misconceptions I have experienced.”

One thought on “Mastering Genealogical Proof – on Sale for 10% Off through Wednesday, Sept. 9, 2015

  1. Does ‘Mastering Genealogical Proof’ book cover international sourcing? I’ve bought book sin the past that are seemingly 80% re: domestic USA research sources and some added bits about, e.g., Scandinavian resource work — which is what my family work IS, not USA.
    Will this help me?
