Ole Brighton Sea Captain, son Charles Aufinson Bri

I recently received Civil War pension information on my gggrandfather Charles Aufinson/Anfinson Brighton who gave information regarding his early life I had not been able to find. I am hoping someone will recognize the names and help me connect Charles finally, to his Norwegian roots. In the affidavit, he states his father was Ole Brighton, a sea captain. He says that he himself was born "on the Baltic Sea between Norway and Denmark." His mother "lived mostly in Copenhagen" but several statements and letters reveal that he was indeed Norwegian. His date of birth is Sept 14, 1842. He stated that he listed Christiana (Norway) as place of birth as it was the closest city of any size. Charles went to sea some with his father Ole, before coming to Qubec, then Montreal and finally Madison Wis area where an unmarried uncle, also named Ole Brighton lived. I am hoping to find some records pertaining to the father Ole Brighton. I do not have mom's maiden name, and it doesn't seem that Brighton is particularly Norwegian.... Has anyone seen anything that could be another version of Brighton? I'm also looking at Braaten, Brixen and Britzein now, but only as I found those on Copenhagen census.
