Background

It is quite likely that many of us, who live close to The Baltic Sea, share a common genetic heritage.
Seafarers, traders, vikings, refugees, and many others have, throughout the ages, crossed The Baltic Sea in a countless number of times.
Many of them did never return to their homeland. Some of them started their new home in a new country, or in an island.
The Baltic Sea also holds the largest archipelago in the world - in number of islands.
Thousands of people live in these islands today, but their ancestors certainly come from somewhere else.
