need research advice - Helleland & Høiland ancesto

Hi all my great-grandparents moved to Australia in 1881 from Stavanger and we have lost all contact with their families in Norway, so I am trying to find them. (their names were Anders Sigmundsen Klungland b1854 Klungland Helleland and Karen Kirstine Jakobsen Dybing b1858 Høiland) these are the people I am looking for who may have also emigrated: *Gabriel Sigmundsen Klungland b1858 klungland Helleland, he moved to Egersund in 1879 *Theodor Sigmundsen Klungland b1861 klungland helleland, he moved to Egersund in 1879 *Karl Johan Sigmundsen Klungland b1864 klungland helleland *Karl Ludvig Jakobsen Dybing (Sjømann) b1853 Høiland, jumped ship in 1878 in London (residence given as Killingland, Høiland) *Enevald Jakobsen Dybing (Sjømann) b1862 Høiland, jumped ship in 1881 in London (residence given as Sandnæs) I have checked the following records at Digitalarkivet: Innflytta/Utflytta for these areas Emigrantar frå Stavanger 1903-1928 Emigranter fra Stavanger 1825-1970 Emigrantar over Bergen frå Rogaland The 1900 census for Norway relevant death/burial indexes this emigrant database but with no success, any suggestions would be gratefully appreciated. thanks
