I am reposting this following failure of server, previous posts lost, fortunately all information given to me by Erudita74 and Marty I added to my family tree in Myheritage.
This is what I managed to collect in the last couple of years:
Margherita Granieri (17) and husband Francesco Mastronardi (30) appear in an arrival document to New York, departed Napoli 26 July 1906 (SS Nord America), arrive New York 9 August 1906, travelling with them was Ippolita Mastronardi (20) sister of Francesco, they declared they were going to visit their brother Antonio, residing in Union Port Road NY.
Margherita and Francesco are my great-grandparents, they emigrated to Argentina, their oldest child was a daughter born in Italy and their second was my grandmother, born in Argentina in October 1908.
I was interested to find the Italian history:
I learnt Nicola Mastronardi (son of Isabella Mastronardi) and Margarita Aliano (daughter of Francesco Aliano and Rosaria Magariello) lived in Stigliano, Via Menotti 1 or 2. Parents of Francesco, Ippolita, Antonio, Giuseppe (died aged 9), Rosa...
Vincenzo Granieri (son of Francesco and Rosa Baffo Cadonio) and Nunzia Fornabaio (daughter of Francesco and Margarita Certosa) lived in Stigliano, but Vincenzo was a resident of Santa Sofia d'Epiro, in Cosenza, Calabria.
I am not sure how to find the marriage certificates of the above... my last question was for Erudita to ask if they were available in Family Search
