Ernestina Bossi (Ernesta Pasqualina Bossi, Mortara 1868 - Milano 1934) was married with Giovanni Valliera, who was my mother's granny. She had two sons: Mario Valliera, my grandfather (Venezia, 1899 - Milano 1953) and Ercole Valliera (Venezia 1897 - Milano 1979). She's buried in Milano at Cimitero Monumentale, grave n. 1350. She's quoted at Teatro La Scala as étoile. I would be very happy to know you, as I have no news about your part of Bossi's family! Please write me:
