I have been finding new information based on my recent DNA test. DNA is a powerful but poorly understood and under-utilized tool. Too many people get a DNA test simply to learn their ethnicity, which is probably the least accurate thing one can do with his DNA. If your DNA has been tested by one lab you should seriously consider uploading the raw DNA file to the other sites that allow it, particularly GEDmatch.com.
Please don't take anything you find here too seriously. Genealogy is like stamp collecting; history viewed through a microscope. It's harmless as long as you don't take it too seriously.
