Any Sirevoogs out there?

Searching for relatives.....my father, Arthur, was born here in Chicago in 1915. His father, John, was married to Inga Andreasson who passed away in 1921 from tuberculosis. John had a brother, maybe 2? Not sure what year my grandfather arrived, but I'm guessing 1908-1912. I believe they were from Stavanger or a small town nearby.
