Name Changes when Emigrated to US from Italy

[milfordcubicle]

Greetings,

I have my jure sanguinis appointment coming up in November 2019 at the SF consulate and have obtained all necessary official records, including my Italian ancestor's record of birth sent from Italy. I am seeking citizenship through GGF-GM-M and meet all the requirements (e.g., GGF naturalized 20 years after GM born; M born after 1948), but am looking through the documents and notice a few discrepancies:

My biggest concern is that my GGF was born Lamberto Attilio Focacci on July 29, 1902 as per the record of birth from Italy. However, the ship manifest and petition for naturalization indicate his name when he arrived as Lamberto Fugazi. The Fugazi name has remained with my family since. His petition for naturalization and death certificate also show a date of birth of July 30, 1902, one day after his actual date of birth. It is generally known that Fugazi is a variation of Focacci (also, Fugazzi), and this surname is really limited to the region of Santo Stefano d'Aveto outside of Genoa, which is where he came from. Luckily, his parents' names (other than the Focacci/Fugazi change) are consistent on the Italian birth record, ship manifest, American marriage and death certificates, so it would be very difficult to imagine that this is NOT the same person. In other words, all records taken as a whole seem to show with some certainty that he is the same person who was born in Italy (the petition for naturalization references exactly the ship on which he arrived and the date of arrival and that his original first name was Lamberto). Are the consulates, particularly SF, strictly by the book with exact names or will they consider all other evidence taken as a whole?

The other concern is that my grandmother's (direct line) name on the birth certificate indicates Lena Vivian Fugazi, but in every other document (and throughout her life) she went by Vivien Helena Fugazi. All other data, including the names of her parents, date of birth, spouse, etc. are all consistent and correct. Furthermore, my GGF (her father) listed her on his petition for naturalization as "Vivian", his daughter with the correct date of birth. I have not checked to see if there was a petition for name change filed in the county she grew up in, but I doubt it.

I do not believe that in California I can amend her birth certificate to change her name without a court order (I am a California licensed attorney and have done several name change petitions), and now that she is deceased I do not believe there is any way to make this change.

Ultimately, my question is whether the consulate will consider circumstantial evidence where there are minor discrepancies, but taken as a whole, the lineage appears near-unequivocally clear. Any thoughts?
