Sverri Gudmund Samuelsen

Sverri Gudmund Samuelsen was born 1885 in Oslo Norway. He had six brothers and one sister. (Names not in order) Samuel b.1880, Alfred, Joseph, Anna, and two unknown males. Father was a Photographer, Karl Anton Samuelsen. Mother was an Opera singer, Marie (Unknown maiden Name). I am interested in any info I can get on this family and any Ancesters. This is the beginning of my search and I am new at this. So I will be happy with any help. Thank You. Debi
