Seeking relatives of Sverre Voien Andersen and Olga Helene Ovetaas — Norway

Hello everyone, My name is Brian, and I am hoping to connect with relatives from my father’s side of the family, especially anyone still living in Norway. I am researching my great-uncle, Sverre Voien Andersen, and his wife, Olga Helene Ovetaas. Sverre Voien Andersen Born: 15 July 1889 in Sandefjord, Vestfold, Norway Died: 4 March 1953 in Oslo, Norway Parents: Martin Andersen and Inga Frantsen, my great-great-grandparents on my father’s side. Olga Helene Ovetaas Born: 1 November 1890 in Arendal, Aust-Agder, Norway Believed to have died in Oslo, Norway; I do not yet know her death date. Sverre was my father’s uncle. My father is still living at 90 years old and has wanted for many years to learn more about his Norwegian family, but he did not know how to go about researching or finding relatives. I am helping him now, and any connection would mean a great deal to us both. Does anyone recognize these names or have this couple, Martin Andersen, or Inga Frantsen in their family tree? We would especially love to know whether descendants or relatives of this family line still live in Norway. We would also appreciate photographs, family stories, information about their children and siblings, marriage records, death notices, burial details, or help finding Olga’s death date. Corrections to the information above and possible alternative spellings are welcome. Please reply or contact me privately if you recognize this family. For the privacy of living relatives, please share their personal details by private message. Thank you for helping my father and me learn more about our family and reconnect with our Norwegian relatives. Brian
