Peter Everson and his son Oliver Everson

I'm looking for any information regarding a Peter Everson and his son Oliver Everson. Peter was born in Norway in 1840 and he was married to a women with the surname Robeck. They had a son named Oliver Everson DOB: 1860. Oliver arrived in the united states in 1886. I was told that he moved to England to be a sea captain. He then moved to the USA and was also a sea captain. I was also told that he worked for the Robert Dollar lines. I can't really find too much information about either of them because my family didn't keep any records. Oliver was my great grandfather who married my great grandmother Amanda Johnson in the USA. He passed away in 1924. This is all the information that I have. His surname could have been spelled different in Norwegian for all I know. There is some information on Ancestry.com about him but not much. Thanks, Nancy
