Thanks for sending me your message Dennis, I appreciate it.
I am doing some research on my end, as the names, places and similarities are too coincidental.
I spoke to my father, and my grandfather's first wife's name was GiGi and she died in the flu empidemic late 1918/1919. The name Casagrande and coming from Valcava, is too weird not to have some connection.
I will research more and get back to you.
Thanks, again........Mary Eccher
