Looking for Robert Berstad

I am looking for any information on a man by the name of Robert Arthur Berstad. His father was named Ander Berstad. When he came to Canada he went by the name of Anderson. His mother's name was Anna Rasmussen. Robert lived in Bergen, Norway and had a brother named Peder Berstad. Once in Canada he married a Signe Lindell(Tegelberg) and had 4 children. Signe and Robert lived a number of places such as Scarth, Oak Lake, Emerson, Fairford, and Lake Frances, Manitoba. If anyone has anymore info on Robert or what ship he may have come over on. Thanks in advance, Leanne Anderson(wife of Robert Berstad's grandson) Leanne Anderson
