Hello, Does anyone know where I can find information on tunnels in the 1875 were located. Especially in the Canton of Berne and in the vicinity of Blumenstein to Thun area. This would be a great help to me to fine my gggrandfather and ggrandfather. Ulrich Eggeman and son Robert Eggeman. Robert b. 1864. immigrated to USA 1884. Roberts mother was Anna whitmore Eggeman. Thank you for any advise on the tunnels. Betty
