Martin Opheim came to Griggs County with his family in 1879. They traveled by wagons, which were pulled by oxen from Decorah, Iowa.
Hattie Stromme was born in Norway and came to this country with her parents, Peter and Elsie Stromme, when she was ten years old.
Hattie Stromme and Martin Opheim were married at Sherbrooke, in Steele County in 1899. Eight children were born to them, two now deceased and six living.
Their first home was on a farm located east of Cooperstown, which is known as the Gust Heinz farm. Later they moved to the Sheyenne River where Kenneth S. Monson now lives. The school was just across the ravine from their house on the bank of the river.
Later the Opheims moved to the Cooper Ranch west of Cooperstown and lived there until 1922 when they moved into Cooperstown.
Mr. Opheim died in 1961 and Mrs. Opheim in 1966. Both were buried in the Cooperstown cemetery.
