The third child of Ole and Mari Finnestad was Maria Olsdatter who died as an infant before my great great great grandparents bought a plot at the Finnestad farm, so Maria never had the last name Finnestad. Because she died in Norway, I do not know whether they had kept death certificates in the 1850's. Maria was born March 7, 1948 and died May 15, 1851.
