The Scandinavian and North Sea line

I1

Where it is common today

Scandinavia and the North Sea countries.

How old it is

This branch split from its parent about 27,500 years ago (between 25,200 and 29,800).

Every man who carries it today descends from one man who lived about 4,600 years ago (between 4,000 and 5,100).

Every test reads your line to a different depth. One report says J1, another J-P58, another a code four steps further down — all of them are right, the longer one is simply more detailed. HealthOS reads as deep as your file allows.
