Is Y-DNA useful for non-Europeans?

Iím trying to get a lead on an unknown paternal grandfather. I do know he is not of European descent, so I donít know if Y-DNA would be worth the cost.


Anyone have any experience with this? Which Y-Dna would be best?

Family Finder may be a more useful test for your purposes than a yDNA test. With Family Finder, you'll get a feature called MyOrigins. It gives an estimate by percentage of your ethnic/geographic ancestry.

The percentages are only estimates and shouldn't be taken at face value or written in stone. However, on average we receive 25% of our DNA from each grandparent, with a small range above and below 25%. Assuming that you know the ethnic/geographic ancestry of your other 3 grandparents, there's a good chance that MyOrigins allows you to infer what type of ancestry your paternal grandfather had. That's especially the case if MyOrigins gives you a percentage that's at least 5-10% of some ethnic/geographic ancestry your other 3 grandparents don't have.

But in a case like yours, testing your yDNA could also be beneficial. If you test 67 markers, you may have matches at that level that give you clues about possible surnames for your paternal grandfather.

So, consider ordering both Family Finder and a 67 marker yDNA test.

Or order Family Finder now, and yDNA as an upgrade (definitely, you want both on same kit!!) later, during a time it is on sale.

By testing Y DNA you are only increasing your chances of finding your patriline family.

Increase by how much? Well, that depends on your patriline original population. For example, British are sampled much better than French. If that population had significant migration to North America, it will likely not matter where their ancestral home is.
