I saw your message and I see that you posted in a while, what you've mentioned has a brother named John Eide who was born on May 20, 1945, well I known long ago a friend from Bergen Norway with the same name and his father's age coincides with the date that you describe, they are both named John Eide and are also from Bergen, I have long time I have not talked with John but I have his mail skype if you want I can put you in touch with him, because maybe is your cousin. Good luck and take care.
