My DNA Journey: Using DNA Companies  to Discover My Father’s REAL  Biological Father by Jim Gunnis on Tuesday, September 3, 2019 at 7 p.m. in the Morris County Library.  

This is an opportunity to gain a valuable new perspective on DNA for genealogy, and what you might do with the DNA results you get.  You’ll learn, or better understand, some key concepts, for example the three major types of DNA tests (autosomal, Y DNA, and mtDNA) and the importance of centimorgans.  You’ll see the value of tests from multiple companies and testing multiple relatives, and why the control data of different  DNA testing companies might skew your ethnic results.
