Bottom of 66r reads like a captcha in Norwegian

As to the title post, I'm afraid it's a bit irrelevant to refer to Nynorsk, as it was developed only in XIX century. (I heard that Norwegian traditionalists do not like Nynorsk ).

Quite right and... Norse names have changed substantially over the centuries. I doubt if there were any or many Norse women named "Jen" in the 15th century, just as there are not many today who are named Unn, Arnvi∂r, Gautstafr, Fri∂þjòfr, or Gu∂fri∂r.
