David, your grandfather was Fedele Tolisano (born 1/15, 1890 - died 1/12/1974) and your grandmother was Dominica Alfano (born 7/22/1892 - died 9/20 1981)--somehow you reversed the names. Fedele's father was Francesco Tolisano and mother, Theresa Senatore---and Dominica's father was Angelo Alfano and mother, Mary Mandisa.
Ciao, Mamma
