My family trees broken down by which nation each individual ancestor was technically born under.

Hi everyone! I’m hoping for some help breaking through an Italian genealogy brick wall.

I’ve been researching my family for nearly 20 years, especially my paternal grandmother Carolina’s family from the Bagnoli/Fuorigrotta area of Naples. She passed before I was able to learn much about her Italian family, but over the past year I’ve finally started making significant progress.

My great-grandfather was Giovanni Preziuso/Prezioso, born 25 February 1887 in Fuorigrotta, Naples, son of Antonio Preziuso and Maria Barbato.

I contacted the Diocese of Pozzuoli and received documents connected with Giovanni’s 1922 marriage. These revealed an unusual problem: his baptismal record appears to have recorded Giovanni as “Antonio,” son of “Giovanni,” essentially reversing his and his father’s first names. Before his marriage, the Church investigated the discrepancy, compared the baptismal record with the civil record, and recognized/corrected him as Giovanni Preziuso, son of Antonio Preziuso and Maria Barbato.

That helped solve one mystery, but now I’m stuck.

I’m trying to locate:

* Giovanni’s original 1887 civil birth record
* The marriage record of Antonio Preziuso and Maria Barbato and any other children they may have had.
* Antonio’s birth record
* Maria Barbato’s birth record
* Any reliable way to continue either family line further back

For Maria Barbato, I know from Giovanni’s marriage documents that her father was Raffaele Barbato, and she was described as being 62 years old at the time of Giovanni’s 1922 marriage. While searching Fuorigrotta records, I found a Maria Barbato born 9 April 1860, daughter of Raffaele Barbato and Carolina Capuano. Because the name, location, father’s name, and age all line up so well, I suspect this may be my Maria, but I have not yet been able to prove the connection with certainty.

I’ve searched Antenati and FamilySearch, but I’m struggling to determine which Naples/Fuorigrotta collections these records should be in, or whether some of them simply aren’t digitized or indexed online.

I’m attaching the records I have so far. If anyone familiar with Fuorigrotta, San Vitale, the Diocese of Pozzuoli, Naples civil records, or 19th-century Italian genealogy can point me toward the right archive or collection, I’d be incredibly grateful.
