Looking for descendants from the following people. 1: Karl ( Carl ) Ludvig Knutsen, born May 20, 1969 in Skudeneshavn, Norway. Departed Stavanger, Norway for USA in 1887 ( ID NO 7996 ). 2: His half-sister, Jørgine Svendsdtr., born June 03, 1857 in Skudeneshavn Norway. Departed Stavanger, Norway in 1883 for USA ( ID NO 24247 ). On arrival in US, she could have used the names Svendsen/Knutsen or Knutson. 3: One more brother, Sivert Kristian Knutsen, born March 16, 1862 in Skudeneshavn, Norway. Family story is that Sivert left his ship somewhere in Australia.Appreciate any help about these people.
