In my family tree I have a similar surname, Nyren or Nyrin dating back to England in the late 1700's, but I suspect the name may either be Norwegian or Norman French originally. The family in England was Catholic, although I have not learned more about its origins there..  Prussia was a very multi-ethnic nation in the 1700's and was also at one time under Swedish  domination. Until the mid 19th century, Norway was considered to be part of Sweden or Denmark.
