Who Do I Think I Am?

So, recently I went through with it and ordered my DNA testing kit through Ancestry.com. It arrived speedily in the mail, and I then spat into a tube, mixed in some blue preserving liquid, capped it off and shook the tube like the Dickens -- and then dropped it off in the mail.

Now, apparently, I wait around 6 weeks to receive my results. What am I expecting to get out of all this? Well, it's mostly to satisfy my curiosity.
