Hi Vito,
I gave you all the Sorrano's I had some time ago. They were:
Antonio Soranno, married to Grazia Abbinante Jan 5 1911 (6 May 1894-27 Jan 1949) and they had Rosa (2 Jan 1912 Carbonara - 1997) and infant Pasquale (1914). I also had Donatantonio Soranno (14 Dec 1878 Sannicandro-?) married to Vita Michela Ficarella (23 Aug 1880 Carbonara- ?) on 13 May 1897. Children were Pasquale 1898 and Pasquale (9 Feb 1899 Sannicandro).
I have checked the Triggiano marriage spreadsheet and there has never been a Soranno who married there 1809-1910.
