GEDMatch Archaic Ancestors: Paleo-Eskimo Q + Ancient African Samples?

Couple of unrelated questions.

1. Are there any ancient African samples included?

2. My husband came back related to the Paleo-Eskimo sample from Greenland. He's American descended from early colonists, most of his DNA on ancestry is British but there's a small amount of Nordic ancestry and I'm wondering if there was documentation of intermarriage between the Norse who settled Greenland and the Inuit (descendants of Paleo-Eskimo people)? His results also connections to Kennewick and Clovis, but so do mine and I have no connection to the Paleo-Eskimo sample. These results are at the 6cm setting.

I'm enjoying learning ancient history using this tool, not taking anything too seriously just very curious if anyone has ideas as to how this came about.
