This is Nils-Magnus’ udde, or Nils-Magnus’s headland, outside Oskarshamn on the south east coast of Sweden. It’s named for Nils-Magnus Carlsson, who was a pilot and the father of my great grandmother Maria Charlotta, born in 1857. I believe Nils-Magnus and his family lived in the house straight ahead.
Maria Charlotta married Carl Victor Nilsson, a sea captain. He has a ground named for him nearby.
