What the tests will tell you is if you you have marker matches with anyone else. The fewer the markers, the larger the generational gap. I did the 12 marker test. I was a test marker match for another person in the clan. He was born in Scotland. The test told us that we shared a common ancestor in the last 22 generations or 400+ years. The more markers, the more they can narrow a gap. At least you are starting off with a larger test.
And maybe you'll find an American cousin.
