While i did study the native Americans, then very little have been saved by my strange grey goo between the ears, but i can tell that reading it was much more interesting then what school had to offer.
There was no Mayflower in Danish history, but looking at genes it do look like we are tied to people coming up from the black sea region as the ice started to melt after the last ice age.
Which seem to be very common as most swing past that region coming out of Africa.
And funny enough that same route Danes used for trade back to the bronze age, and the later vikings established many towns in that direction, of whom many still exist.
Strange things come up of the Danish dirt some times, one thing like the Gundestrup cauldron are still much debated in its origin, cuz its not made here for sure.
They do agree on it date to about the time of Christ.

We traded in Amber mainly that was much sought after down south, so that paid for a lot of bronze and other things.
