Gust Sunde

Hello again! I just learned that my great-great grandfather, Gust Sunde, emigrated here from Norway. I don't know much else, except that he first married my great-great grandmother, Marne Brenne? either here in Minnesota or in Norway. She died around 1898, when my great-grandmother was 2 or 3, in Herman, MN. Any information you can find on either of them? Thanks! Shari
