Alvilda Bergh

I am trying to find where Alvilda Bergh came from in Norway and her journey over, her headstone with bo birthyear or deathyear is at the Naples cemetary close to Mondovi in Buffalo county Wisconsin, Alvilda is possibly relation to a Andreas Bergh, Andreas and Sjur Peterson Overboe 1822-1914 gave land to the church and cemetary there in Naples, pictures of the old church and homestead close to the church is welcomed too, many thanks.
