I have found the Vossboki (book of Voss family and farm history) online, but it is in Norwegian.
I found this tidbit about the brother of Lars, who had lived at Klyve (Kleeve?) farm before he came to American. Maybe they used that last name after they got here?http://www.ullstad.com/vossaboki/klyve.htm
kom Brynjulv Håkonson Ukvitshaugen, g. 1874 m. Kristi Eiriksdr. Kytesgeilane, som reiste til Amerika.
Then came Brynjulf Håkonson Ukvitshaugen (Opkvitneshaugen)) married 1874 with Kristi Eiriksdatter Kytesgeilane, who emigrated to America.
Here is the page in the Vossiboka which mentions this family, at the almost very bottom of the page under Husmenn, (tenant farmers) Not very enlightening!http://www.ullstad.com/vossaboki/ukvitno_i_reppen.htm
Håkon Sveinson f. ikr. 1819, g. 1848 med Sigrid Brynjulvsdr. Bulko. Dei hadde borni: Lars f. 1850, Brynjulv f. 1853, Svein f. 1861, Ivar f. 1865, Synneva f. 1856, Anna f. 1858, Kari f. 1872.
Håkon Sveinson, born about 1819, married 1848 with Sigrid Brynjulfdatter Bulko. They had children: Lars born 1850, Brynjulv born 1853, Svein born 1861, Ivar born 1865, Synneva born 1856, Anna born 1858, Kari born 1872.
That information was gleaned from the 1865 census, so we already had that.
Då dei flytte til Kvitno, kom Brynjulv Håkonson Ukvitshaugen, g. 1874 m. Kristi Eiriksdr. Kytesgeilane, som reiste til Amerika.
