This is the first genetic genealogy workbook. This book covers the biological basics, types of DNA testing that are useful for genealogy, and analysis techniques needed for successful genetic genealogy. No matter which company a person tested at or which tools are used for data collection and analysis, the information in this book will help a researcher correlate DNA evidence into a family study.

For more information please see this page which includes links to a topic list, reviews, and awards.

• An Identity Crisis: Using Indirect Evidence to Prove That H. P. Davis and Passen Davis of Trinity County are One Man Who is the Son of Wiley Davis
  A case study demonstrating use of multiple indirect sources to prove that multiple names and initials used in multiple locations all refer to one man. Published in Stirpes, Texas State Genealogical Society, March 2011.

  This essay tells part of the life story of Henry Parker (1823/1825 to 1902) and Nancy (Black) Parker (circa 1835 to 1902). The story is based on research done as part of a multi-generational study of this Parker family. Many facts on this family and the collateral relatives could not be included due to word count limitations. Future publications are planned to allow a more complete story of this family to be told. Endnotes instead of footnotes were requested by the contest committee. Second-place winner, Dallas (Texas) Genealogical Society Writing Competition 2012 (DGS, http://www.dallasgenealogy.org/).
