These are nearly all from 23andMe, matching on just one segment. Since my grandmother's Finnish ancestors arrived in Norway around 1600, and Finns are an endogamous population, chances of determining a MRCA for very many of these matches is fairly slim. On the bright side, wherever my family matches Finns the chances are good that this is through my Hedmark great-grandmother (who has the known Finnish ancestry) rather than through her husband, although as Finns settled in many parts of Sweden and Norway, Finnish ancestry cannot be ruled out for any of my Norwegian immigrant ancestors.
