My grandfather married a Elina Erdahl(1880-1899) in 1897 or 1898. They lived near Norwegian Grove , sibley county in minnesota. She was the daughter of Maldi and Halvor Erdahl. She had a sister Sonneva Erdahl Halvorson (1871-1897). There possibly was a brother named Tosten? Does anyone know them or where they were from? Elina, her sister and their mother all died from consumption (TB).
