Thank you for your pm's. Pleased this helps to give a bit of background for you. We know Grandizio started off in Pennsylvania because 2 of the chilldren were born there and we have managed to find him on all 3 census - 1910/20/30.
Giambattista (born 1882) (another brother of Florinda) was in Scotland by 1901 and shows on the Scotland Census.
Agostino 1885 arrives 1907 but by 1916 he has died - not sure if he married or not.
Stefano 1876 was married to Almerinda Franchitti - they had 4 sons but they have disappeared but we think he died before 1921. (I wonder if he was still in Pennsylvania !!)
Grandizio sponsored Almerinda and 4 sons to go to Atlantic City after the death of Stefano.
In that 1920 census of Atlantic City Ward it shows Millie and Joseph Zona. Millie was Carmela Cocozza - daughter of Grandizio. Millie and Joseph have at least 7 children. One of which was Leanore. (I have found an obituary for her which gives details of her husband and children - will send by pm)
Peter Anthony Cocozza 1910 New Jersey married Nellie Viola Smallwood and it seems had at least 14 children - the first born son 1932 died 2002 in Egg Harbour. Atlantic City.
So plenty of info on the Cocozza line but nothing leading to Umberto Schiavone or anymore of his family.
Any more clues you can give me ?
