Ep. 28: Italian Ancestor Name Changes | Connected an Ellis Island Immigrant to His Naples Birth Record

He arrived at Ellis Island in 1912 as Salvatore Maranzano. He reappeared in the 1920 Census as Samuel Martin. Eight years of silence in between, and three years of searching by his granddaughter had turned up nothing.

In Episode 28 of Ancestors and Algorithms, we follow this real listener case from start to finish and show you exactly how three free AI tools, Perplexity, Gemini in Google AI Studio, and Claude, solved an Italian immigrant name change mystery that stumped a family historian for three years. From a Declaration of Intent buried in NARA records to a Catholic marriage record in Brooklyn to a civil registration birth record in Nola, Naples Province, Italy, we follow the paper trail all the way home.

You will walk away with five copy-paste ready AI genealogy prompts and a complete workflow you can apply to your own Italian or immigrant family history research today. All tools featured are free.

WHAT YOU WILL LEARN IN THIS EPISODE:

The truth about Italian name changes at Ellis Island. Immigration officials did not change immigrant names. The manifests were created in Italy before the ship ever left port. So where did the name changes actually happen, and why? Perplexity gives us the full answer, with cited sources.

How to use Perplexity to build a research map before you ever open a genealogy database. We ask three targeted questions: why names changed, what records document a legal name change, and where naturalization records, Declaration of Intent files, and name change petitions are held today.

How to use Gemini in Google AI Studio (free at aistudio.google.com) to transcribe handwritten historical documents you cannot read on your own. Gemini 3 Pro now achieves expert-level accuracy on 18th and 19th century handwriting. We show you the exact prompt that revealed a hidden intermediate name in a 1914 government document, the clue that cracked this entire brick wall open.

How to use Claude to analyze multiple documents for the same ancestor, build a chronological research timeline, identify gaps in your evidence, and flag inconsistencies in names, ages, and birthplaces before you commit to a conclusion.

How to use Antenati, the free Italian State Archives portal, to find Italian civil registration birth, marriage, and death records. We trace our ancestor from a Brooklyn barber shop back to a birth record in Nola, Naples Province, using a column on the Italian-side ship manifest that most researchers never think to check.

These techniques are not limited to Italian genealogy research. The same AI-assisted workflow applies to any immigrant ancestor who appears to shift identities between the old country and the new one.
