I know this could be a stretch, but I noticed that the areas you are seaching in WI are Pierce Co. and Stanley, Chippewa Co. You also mentioned following other lines. Just by chance are you looking for any Olson's or Simonson's in these areas?
I have a g grandfather that was born in River Falls, Oluf Olson and his wife died in Stanley, Minnie Simonson Olson. Their daughter Winnefred Olson was born in Stanley, she is my grand mother on my fathers side.
Thanks for checking.
