I am looking for information on Ludvig Carlson.

His son was Daniel William Carlson who was born on April 17, 1899 in Virginia, St. Louis, Minnesota and died on June 6, 1942 in Honolulu, Hawaii while serving in WWII.

I think Ludvig may be from Sweden. I do not know his wife's name of the name of any of their other children if they had any.

Any connections? I have searched records on here as well as the records online in Swedish. I think the name Carlson is confusing since it has so many spelling variations...
