About Marc McDermott

I’m Marc McDermott, an investigative genetic genealogist and the guy behind Genealogy Explained.

I started this site years ago as a way to document my own genealogy research and share what I was learning along the way.

I never expected it would help thousands of people navigate their own family history journeys.

My work also extends beyond this site. I assist law enforcement with cold cases involving violent crimes, using genetic genealogy to develop leads for investigators.

I also volunteer with the DNA Doe Project, a non-profit that uses cutting-edge genetic genealogy to identify human remains.

Feel free to connect with me on LinkedIn.
