Is it possible that for business purposes, even back in the first half of the 1800s, that a family would alter its name for ease of spelling and reading or any other business purpose?
It's a question because I have every reason to believe I've 'found' family in the San Ferdinando district of Naples. The names in the records are much 'fancier' than the name the family used for their recognized printing business in Naples (and the name by which they were known across Italy).
I hope any or all of the readers will contribute whatever they may know about name changes to this question. I'm asking about changes in Italy, in the first half of the 19th Century, not as happened with immigrants arriving or staying in America.
In my research I have found to follow in change of spellings of your surname to be acurate you have to follow the records and find marriage and death records that show a change in birth towns and follow them back. I started in Trabia Palermo films got the records followed all the domiciliato in Trabia (living in Trabia) and nato in Trabia(born in Trabia)on the records until they changed to different birth towns and residing in towns and as I went through the records I would find sometimes a change in the surname from town to town maybe a letter sometimes more than that. Just kept researching and verify my history with records not taking any ancestry tree info unless they could backup with paper.
