Hello again Joanne
Have you done any further research? I have and can tell you that your fathers grand mother name was spelled Di Lorenzo not De Lorenzo. I know this because my fathers grand father name was Giuseppe and his parents were Giovanni Isabella and Filomena Di Lorenzo thier kids were: Tommasso (b) 11 MAR 1866, Giuseppe (b) 1864, Constantino (b)3 OCT 1873 and a sister Venerata (b) 1 AUG 1876. Did you know that there was also a son who died named Constantino? he was born 5 oct 1871 but died before 1873.
