Anton and Nikoline Gregersen were my husband's great-grandparents. They moved from Oregon to Washington State between 1910 and 1920. Anton died 6-2-1960 in Edmonds, WA and Nikoline died in Alderwood Manor, WA on November 7, 1948. I cannot find any record of their eldest son, Herlof Cornelius "Harold" Gregersen, past the 1920 census, where he was 24, single and living with his parents. Gerda "Constance" married a man by the name of Days, with whom she had a son Wallace Day in Oregon in 1917. By 1920, she was widowed and in 1923, she re-married a Charles Harrison in Vancouver, BC, Canada. Erling "Samuel" wed Ethel Peterson in the mid 1930s and had a daughter, Gem Rhoda Gregersen, 5-15-1936. Samuel died in July of 1967.
