I just read your posting. My Grandmother, Martha Ohnstad Rensvold, was the daughter of Mons Ohnstad. She was born near Gardner, N.D. on the farm. She married Herman Rensvold and had two daughters, Helen Marilyn Resnvold Anderson, and Pearl Rensvold Backstrom. My mother is "Marilyn", she has never gone by Helen but was given that H.M.R. initials to match her father's initials. My Grandmother, Martha, was given the trunk which has been passed down to my daughter, Martha Marie Sortland. We have been to Aurland and had the opportunity to visit with Anders J. Ohnstad. I remember the Cordal name and I believe I gave either Ida or Thea a ride back to Fergus Falls with my great Aunts when my grandparents had their 50th anniversary. My name is Carolyn Faye Anderson and I am married to Paul A. Sortland and we live in the Twin Cities. My Great, Great Grandmother was Kristana Ohnstad.
