Researchers from Norway, Britain, Iceland and Hungary met in Stavanger this weekend to work out the guidelines for the tests.
The project is a continuation of a DNA test carried out by Professor Stephen Harding from Nottingham, on 150 persons from Wirral, near Liverpool.
- We found that half of them had Norwegian ancestry. We will now try to see if the same is true in other regions in Northern England, Harding says.
It is believed the first Vikings settled at Wirral in 902.
