Sorenson Molecular Genealogy Foundation expands Y-DNA database.
If you're using DNA testing to further your family tree research, you'll want to experiment with an expanded online resource. The nonprofit Sorenson Molecular Genealogy Foundation's (SMGF) <www.smgf.org> Y-DNA database now includes more than 12,000 genetic profiles. They're linked to genealogies that document 480,000-plus ancestors representing at least 7,900 surnames around the world.
Search for potential ancestors by entering the numerical values from your DNA test results into the database's drop-down menus. Since men carry the Y chromosome, women need to use a male relative's test results. If you haven't had your DNA tested, you still can see what search results look like — just select Use Demonstration Values.
