According to my great-aunt:
Soren Paulsen SOBY was born in Denmark, 1838. He married Anna K. B. MUNCH in 1878. She was also born in Denmark, 1848. She had a son, Charles Swert JACOBSEN, from her first marriange. Soren and Anna's son, Soren Paulsen Munch SOBY was born in 1885 in Minnesota, USA. I have in my notes that Anna immigrated to the US in 1882.
