From Kviteseid , Telemark to USA

Gunleik Folkvardson Lier and wife Ingrid Ouversdaughter had 9 children on their farm Lier - near Kviteseid in Telemark. 7 of the children emigrated to USA. We do not know where or when they went. The only one found on ships-list is Ouver born April 13.1864. He went to New York on Sept. 1883 on the ship Rollo from Oslo. The others we are looking for are: Svend born May 23.1859, Ingebjørg born January 16.1861 - she was possibly married to Aasmund Nestebø and Jon Sandbrekklid in the US. Thone(female) born October 9.1862, Tollef born January 2.1868, Eivind born April 9.1870 and Sigrid born January 4. 1872. Their surname should be Gunleiksen or Gunleikson, but Ouver used Gulliksen when he left. Can anyone help us trace them and living relatives? Thank you from Turid
