I know yours is a very old post, but am sending this in case you've discovered additional information. Here's what I know, briefly, about my Hedberg line:
My GGrandfather,Alfred Hedberg (b.1854) came to Chicago in 1870, married Anna Perrson/Person/Pearson (b.1846 or 1847)in 1879, had my grandfather, Alfred Hedberg, in Chicago in 1879 and the family is in the 1880 census in Georgetown, Colorado. They had three other children: Arthur Wilhelm, Amanda Axelina and Walter Evald Hedberg.I think Alfred (b.1854) was from Sodra Ny, Varmland, Sweden. The last information I can find on Alfred (b1854) is in the 1900 census and he's in Shoshone, Idaho.
