Torger Sjurson Hove

Torger Sjurson Hove, (b.1823) and his wife, Anne Knudsdaughter, (b.1834) emigrated from Norway to Minnesota in 1858. They had one son, Knud, b. 1855 in Norway. I do not know if Knud emigrated togehter with his parents. Torger and Anne got one more son, Gulbrand, b. 12.03.1866 in Freeborn, MN. Now I ask for help to find if Torger and Anne got more childern in USA ? And did Knud emigrate to USA togehter with his parents ? Bjørn Dahler
