I am trying to find information regarding ancestors who originally came from Hidra, Norway. Katrine Nilsen, born 1885, twin of Nils Nilsen, who married Otto Olsen Fidje and settled in Brooklyn, New York. In 1930, they lived in Brooklyn with their children Mable, born 1913, Edward, born 1916, and Olaf, born 1918. Didrikke Nilsen, born before 1885, who married Marcelius Hansen Langlandstrand and also settled in Brooklyn, and had a son named Magnus Dagfin Hansen. Also, Olava Nilsen who also married an Olsen and settled in the United States. I am interested in any information regarding all of the above and their descendants. Edward Olsen was killed in WW ll. Any or all of the above might have returned to Norway.
