Joe A Boyd

My 2nd gr grandmother was Sarah(Siri) Thorson, b Feb 10, 1842 in Fjelberg, Rogaland. She died Feb 18, 1933 in Illinois(?). They had a daughter named Thine(Tena) Boyd (Oct 10,1868-July 15,1963) born in Etna(?). I'm trying to find any information regarding their immigration and her husband Joe Boyd(1838-1902), probably English or Irish. Thanks
