Looking for info on my gr. gr. grandfather, Nicolai DANIELSON, who died in the 1870's. His widow, Anna, is listed on the 1880 WI Federal Census with 4 dtrs and a son: (Greta) Mathilda; Hannah; Emma; Nellie; Dedrick (son). They all moved to Milwaukee, WI by 1900. Dedrick died young; all 4 dtrs married in Milw.Need help finding out what happened to Nicolai.
