Elizabeth Shown Mills, author of Evidence Explained, was recently featured in a video on You Tube. The title of the video is "We Are All Cousins."
The thrust of her message is that we need to broaden our research to include ethnic, religious, and geographic groups that we may believe do not apply to us. If anything, the application of DNA technology to the field of genealogy shows us that the way we look or the stories we have been told are often misleading indicators of our heritage.
The video is short and to the point: cast a wider net in your research. You can see the video at http://www.youtube.com/watch?v=lY42QvEaV88
