I'm seeking information about a John Kost who lived in Minnesota (Minneapolis area) around the turn of the century. He was married to a woman named Sophie (or Sophia), and they had two sons - Walter Kost (born 1898) and Wallace Stanley Kost (born 1912).
John ended up leaving the family (for reasons I don't know), and Sophie later remarried after her sons were grown. I know little else, including when John was born or when/where he died. He may have been born in Poland, though I am not certain of that.
Any information would be much appreciated.
