Surprisingly strong DNA link with Norwegian.

Thank you.  I only have Quote, but not Modify.

Thank you everyone for your replies. There is an additional mystery. I share this Norwegian’s DNA with a descendant of my great grandfather’s sister. She shares about 300 cm of DNA with him. This makes me think the shared ancestor of the 3 of us is her great grandparent and my great great grandfather parent. My gg grandparents moved from Somerset to Bristol which is a port city. The Norwegian has one ancestor of about the right age who was a sea captain.
So it seemed very likely to me that we are all descended from the Norwegian Sea captain.
However, there are some spanners in the works. My great grandfather and his sister were born about 8 years apart and other children were born in between. Would my great grandmother who was married really have gone back to the sea captain each time he visited, if indeed he did visit Bristol?
Also, although there appears to be a strong link to my Somerset ancestors via my maternal grandmother’s father, I and the Norwegian share many smaller dna links with my maternal grandmother’s mother’s ancestors in Cornwall.
Could it therefore be just an anomaly that I share more dna with the Norwegian than should be expected and actually he’s a more ancient Cornish link, or both?
Please excuse my convolution.

Not to those extremes but my Ancestry DNA shows 7% Scotland, 3% Sweden and Denmark, and 2% Norway, so that's 12% i have no idea of   My 40% Ireland, 27% Wales, and 21% England and NW Europe seems more logical.
