Hi - I am also researching the DiNardo family from Sant' Eufemia. I recently found out that my great-grandmother's name was Lucia DiNardo. She was married to Teodoro DiPietrantonio and two of their children were Anna Concetta b. around 1883 and Carmine (given name: Donato) b. 1885. Carmine was my grandfather.
I know we had relatives in Alquippa - which I saw you mentioned in one of your postings. So I was wondering if we were conncected somehow.
