I'm seeking information about Robert Gaertner or Gardner born about 1825 and died in 1886 in Olmsted, Minnesota. He married Josephine and they had at least two children John Robert (1854) and Emma Elizabeth (1865). Emma married a John Seward and John Robert (my great grandfather married Frances Seydel and moved to Chicago. A third child, Louisa Antonia, born 1860 may have died early. I can't find any information on how Robert Gaertner (or Josephine) arrived in Minnesota. They are both believed to have been born in Germany. He indicates he came over in 1855. Looking for those who share these ancestors, or common DNA and hoping to break through this brick wall.
