Search Family Names, Sabey, Kruge, Hoff

My great grand parents on my maternal grandfathers side came from Norway between 1863 and 1890. My grandfather was Byron Sabey, was born in Chicago in 1890. His father was Christian Sabey from Bergen. He had several brothers, one was Lewis Sabey who eventually became a doctor (went to Johns Hopkins) and wound up in Paia, Maui, Hawaii. I cannot locate information about him or any other person in Norway with that last name. Christian's wife was Beatta Kruge from the Larvik area. She had no siblings. Her parents were Anton Olaf Kruge and Beatta Hoff Kruge born about 1830 in the Larvik area. They were married in Larvik. Here too, I am striking out in finding the family in Norway. If anone can help I would be most appreciative. Sincerely, Byron Peterson
