I am looking for more information about my great grandmother, Olivia Nielson. She immigrated to America from Lillisand, Norway in 1901 and married Thomas Thompson, who was born in Bergen, Norway and immigrated to America in 1883. They had 13 children, of which my grandmother was one. I have found records of them living in NYC with thier children in the 1920 census, and have found them again in the 1930 census living in Texas. Any information about Olivia, her husband, or thier parents/siblings would be appreciated. I have extensive tree information about thier descendant, just little about them, themselves.
