It's good stuff. My ancestors are somewhat easy to keep track of, going back several generations, because they all settled down in Nebraska. Three of my four grandparents were born there, and the other grew-up there. I haven't done any testing to see what is mixed into the core of my Czech, Slovenian/Greek, Irish, and German. With Europe, you know there always winds up being some Scandinavian and Low Countries, when all is said.
You would prob find it very interesting once you start traveling down that road...
I have been looking into mine for a couple years, although not the entire time as you hit road blocks, perhaps that will remain unknown.
Since you have a foundation it would perhaps be easier for you, even w/out a DNA test.
The Mormons have a great site that in some ways is better than some of the others & you don't need a DNA & is no cost to you.
