Immerse yourself in the world of investigative genetic genealogy. Following the interactive, hands-on clues provided, you will take a front-row seat in this fun and exciting three-hour event, attempting to capture a killer from the 1970's. No previous experience necessary. However, with your newly-minted genetic genealogy expertise, you may just find yourself up all night doing your own family history when you return home. (This is your fair warning!)

with Diahan Southard

Let's get the tech out of the way and get down to the hands-on business of creating a group of DNA matches who can help us find our missing ancestor. Using fun, brightly-colored interactive cards along with a workbook and detailed instructions, you will find yourself finally understanding how to solve a family history mystery with DNA.



talk with Nathan Dylan Goodwin

This talk will give an overview of the investigative genetic genealogy process: what it is, where it is used and the basics of how it is undertaken. Nathan briefly discusses some real-life key cases that have used IGG and then demonstrates IGG in action through his own fictional writing, focussing on the Venator Cold Case series.

There's more to explore than just your autosomal DNA test results. Both YDNA (for direct male lines), and mtDNA (for direct female lines) can add to your genealogical research. But only if you know how to use them!

Praise for GSI events:

"I loved this adventure. It was the perfect combination between entertainment and a learning experience (or a practice experience for the more experienced) As a genetic genealogist that usually works solo, it gave me the opportunity to experience working as a part of a team and that is precious. I learned a lot about myself but also the adventages of bringing several minds and having a "think tank."

Janna Helshtein

"It was a thoughtfully planned event. I made friends. I was able to get a bigger picture of how forensic genetic work is done. It was fast paced and didn’t drag. It was professionally done. All of the people on the presentation team were kind and generous and friendly. I absolutely felt like I got my money worth.... It was so well thought out. All of the details were impressive. And impressively engaging. I think it was an impressive way to abbreviate all the steps and yet let us get a taste of all the steps."
