Hi Mary-Kaye,
Thanks for the quick response and info. I think my next steps will have to be contacting the parish in Italy where my grandmother's family is from. The history is just too sketchy. Again, my grandmother's mother Rosa died young. She was raised by Rosa's mother. Also it would seem that your great grandmother Michelena would be in the age range of my grandmother's grandmother. Again, what caught my eye was the Landi name because my mother's family were so close to them many years ago in Manhattan. If I eventually uncover anything of interest, I will certainly contact you.
Thanks, again.
