I am looking for any information, though preferably info before 1870, on the family of
Peter N. C. Kalberg (b. 1829-Norway, d. aft.1890-WA)
& Anna Catherine Robinson (b. Feb 1841-Norway, d.aft1900-WA).

They had 5 children that I am aware of, though the 1900 Census says she had 10. The 5 I know of are:
Henrietta (Hattie) E. Kalberg (b. 12 Jun 1868-Chicago, Ill.)
Randolph M. Kalberg (b. 02 Jul 1870-Chicago, Ill.)
Anna K. Kalberg (b. Oct 1872-Ill.)
Edwin M. Kalberg (b. 1876-Wash. Terr.)
George C. Kalberg (b. 1879-Seattle, WA)

Any help would be greatly appreciated.
