My maternal grandmother, Carmela Mercante Dispenza, had a sister, Angelica Mercante, who married a man named LaPorta and moved to Chicago. I don't know how many children they had.
Angelica was born in Villa Frati, Sicily in the mid 1880's. Besides Carmela, her other sisters were Margherita, Giuseppa (Josie), and Nunziata (Nancy). Their parents names were Antonino & Maria Mercante.
If this sounds familar to anyone, let me know.
