I have spent more time than you would ever think possible wondering how I can narrow down the origin of my ggg grandfather Raffaele Ciaccia.
He was born around 1790, was in London by 1812, and only once, in the 1851 census, have I found his birthplace listed as Naples rather than Italy or 'foreign parts'
Having thought a lot about the situation in Italy at the time, I wonder whether he referred to the Kingdom of Naples, as it would have been when he left, rather than the city of Naples.
The name Ciaccia seems most prevalent in Sicily, which would have been part of the kingdom at that time.
Of course this is broadening my possible search area rather than narrowing it down.
Opinions from the historical geniuses among you would be welcomed!
