Relatives in Fitjar, Hordaland, Norway in 1865-188

1) I am looking for information on my Norwegian ancesters. Jens Poulsen AKA Jens Paulsen was born 9/19/1829 in Stord, Hordaland, Norway. Who were his parents and where did they come from?? According to the census, Jens lived in 1865 on a farm-Rimmereide- in Fitjar, Hordaland, Norway and also in 1875 with his wife, Barbra Andersdatter, and children. What year did Jens Paulsen die and where? Did he emigrate to the USA and when? 2) I am looking for information on my great grandmother, Barbra Andersdatter( AKA in the USA as Barbara Anderson). She was born 7/14/1829 in Ulvik, Hordaland, Norway. Her father was listed as Anders Jacobsen and her mother as Donneal Svendsdr. When she married 8/4/1860 in Stord, Hordaland to Jens Paulsen, her father was listed as Anders Gabrielson. Who was her true father? When did she emigrate to the USA? I have not found any US census data with her name.
