I have a Anthony Harris Kvam b in 1957 and I believe his father was Bernard Norris Kvam b in 1920, and his afther again was Sivert Kvam b in 1885. His father again I believe was Bernt Olsen Kvam who was born in Norway. If this seem to fit with your information, there are descendants of Bernt Olsen in Norway who I am sure would love to get in touch with you.
