I am also the gg granddaughter of Daniel Northrup and Winnifred Bailey Northrup. I know very little about them. Their graves are in a nice little cemetery called Oak Land which is on the right side of the highway 371 just about 8 miles south of Brainerd,MN. It is just north of the wayside rest there. They do not make certificates that old at the historic courthouse. They told me to just look in the books for the information. I went next door to the history center and museum in Brainerd. They are going to send an obit to me. I haven't gotten it yet. The machine was busy when I was there. I live about 4 hours south. I think they would send one if you contacted them. Their daughter, Eliza Josephine Flansburg, who was married to Peter D. Flansburg lived near St. Mathias, MN and are both buried in a small cem. near the town of Ft. Ripley.
