I am looking for descendants who are researching this family. Gustav Adolf Blomberg, b. 1825 in Sweden, married Sara, who died in St. Peter in 1875. They had sons - J. Albert Blomberg, b. 1849 and d. 25 May 1914; Gustav Adolf Blomberg, August, b.1856; and August Blomberg, b. 1860. Any clues as to where to look in Nicollet County would be greatly appreciated.
