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.
“We have enhanced the database’s genetic matching capabilities to increase the number of results from each query,” says Ugo A. Perego, SMGF’s director of operations. You can customize your search to return matches for all, 85 percent or 70 percent of your DNA markers. Each match links to a pedigree chart, which in turn links to family files on the Church of Jesus Christ of Latter-day Saints’ (LDS) FamilySearch Web site <www.familysearch.org
>. (SMGF is quick to point out it’s not affiliated with FamilySearch or the LDS church.) You also can see a graph that shows you — albeit in somewhat cryptic fashion — the likelihood that you share an ancestor with the matching person at any one ancestral generation.
