While I think people from the Maritime Archaic probably crossed the ocean and landed in Scandinavia, I think the use of red ochre is too common to be strong evidence. But it's interesting, so we can add this find to others such this genetic anomoly (Y chromosome haplogroup Q-L804) which diverged from it's closest clade in about the same time frame as this cemetary.
Do you know where Q-M1107 and Q-M930 were located?
All of the other boxes have locations associated with them.
