Here is the obituary* for Ole and Mari Finnestad's granddaughter, Mary Elizabeth (Knutson) Olson.
Mary was born in Stavanger, Norway on May 16, 1867 as Maria Berthea Knutson. Her parents were Elizabeth (Olsdatter Finnestad) Knutson and Ole Andreas Knutson.
Unfortunately the obituary did not mention Mary's siblings; I am still missing one of the ten children born to Elizabeth and Ole Knutson.
