Justina Vedin

My great grandmother was Justina Vedin, her and her 9 children were on the tragic ship Norge when it sank. Only my Grandfather Martin Vedin (Wedin), and brother Ture survived this horrific episode...eventually meeting their father Martin here in America (Upsala, MN). I have been trying to locate any family in Sweden, but it has been very difficult tracking. Justina and children left Borgvattnet to meet her husband Martin in MN...can anyone help? Thank you,
