Go on then, prove it using DNA tests.
Or I will continue to believe you live in a fantasy world ;)
I can't prove it with DNA testing because I don't have ANY matches haha. Some of you Poles should start getting tested so I can prove it with DNA ;).
I do have Birth records on the other hand that can get my back to my great grandparents on my grandfathers paternal, and maternal side...both of which trace back to Poland. As far as the paper trail, and word of mouth can prove...I have about as much proof as a person can get to say that I am at least half Polish.
And now let's be serious- are you really interested in your ancestors from 11th century? It would be nice to know that but just as some kind of curiosity. And btw- DNA test are only showing you some traces and don't tell you anything really important.
I think it'd be very interesting to get back to the 11th century, and why stop there? You have to remember that I'm one of those people who will, by his own choosing, sit down and read a history book...especially if it has to do with European history. It's not just about finding my 30th great grandfather, it's about learning the stories that go along with the names. Every person has contributed to the world in some form or another...some have left a larger mark than others, but none the less, they've all left a mark of some kind. The paper history of census records, birth records, marriage records, as well as the written stories about the people are just part of genealogy and history. You also have the history that runs through every persons own body. We all have DNA that can date back thousands of years so some man or woman who had their own unique story. Then you also have the visual art of history in heraldry. The coats of arms that were passed down from father to son, and were either kept the same, changed slightly, or even quartered to include the mothers paternal heraldic device. There are many elements of history, and I think they're all interesting.
DNA doesn't stamp out my family tree out for me. I still have to do some work to figure that out, but none the less it will give me genetic cousins and that's how you get your answers. It's a team effort for sure to use DNA to your advantage, but when done right it can make connections that you would never find, or take a very long time to locate.
