I think I am connected to this family.Martin Madson married Wahlborg Louise Ostlund. Walborg's sister was my grandmother.Martin and Wahlborg went on to have at least 9 children, 4 boys and 5 girls according to the 1910, 20 and 30 census. Martin died 1933 or 34 and Wahlborg died in 1937. They remained in Carlton county until their death.
I found Martin in the 1900 census living with his father, mother and several siblings.
