Antonius Severinsen

Does anyone out there know what happened to Antonius Severinsen? He was born 28/9/1863 in Okendal, Nwy to Severin Olsen and Ellen Anthonsen. He was the Sheriff in Mojoen. A distant relative gives the following story about him. One night Antonius came around to a farm where Julianne Larson lived with her brothers, to check on the farm. He saw Julianne & took her and was never heard from again. Out of that a girl named Borghild (my mother) was born she was raised on the farm. Antonius was never heard from again. Julianne on the other hand subsequently had a boy named Fredoff or Frithjov without being married. She did later marry the father of the boy. The fathers name was Jorgen Oseng, with whom she had three other children, one boy Kare and two girls Eli and Ingrid. We have never been able to get any information on Antonius and need help.
