Another Ottersdatter search

Hi - long time since last time! Perfectly guided and assisted by Brining, Hopkins and a few other advanced members, I succeeded in getting contact with "My American Family" - whereof two visited us in Oslo last summer! Thanks a great lot to all good helpers! Next hunt is for Sirianna Ottersdatter's three sisters, Ingeborg Ottersdatter (b. Bardu in Norway 1857), Mary (Marie) Ottersdatter (b. Tylldal in Norway 1836) and Marit (b. Tylldal in Norway 1833). Marit emigrated with her foster parents some time after 1845. Her foster parents were Ole Olsen Brandvold and Kari Jonsdatter Bondåsen, both of them from Bardu. They most likely settled in Polk county, Minnesota. Marie emigrated some time after 1865 and Ingeborg as late as 5th May 1900 with her son Ole Ingvard Johansen. (As for Ingeborg and Ole Ingvard, there are indications that they went to Canada). This is too big a challenge for poor me.... Best from [:p]
