I've decided to delve into the world of tracing my DNA and have been doing some preliminary research online. So confusing!

Can anyone recommend a specific company out of the many that are out there?

First and foremost, I want to know which ethnic group my ancestors come from on my maternal and paternal sides (my brother will provide the Y chromosome) in Africa.

Secondly, I want to know about my other heritages as well. Like my Native ancestry (I'm told it's Seminole, which in itself was a mix of different ethnic groups) and my Irish ancestry (which I have on both my mom and dad's sides).

Can anyone out there who has had specific experience doing this recommend one?
