I may have been aware of the fact that that’s sort of what I was trying to say, but I didn’t have enough knowledge to distinguish “common law” from “civil law”, despite having the ability to actually define common law as it is. I didn’t have the term “civil law” is what I’m saying. Thank you for that. There was a gap in my knowledge and you patched (at least some of) it.

I wasn’t specifically aware of when common law started. I looked it up just now, and apparently “in the courts of English kings in the centuries following the Norman conquest”. So… perhaps it’d be more accurate to imply common law is Nordic as opposed to Roman? In a very indirect way.
