Trying to find a name change document

[RosePapa]

Hello!

I am trying to find out if it is possible to find a name change document for my great-grandfather. He was an illegitimate birth, and was placed in a foundling home, where he was adopted shortly after his birth. I have found his birth record, which lists his name as something completely different from his adopted name. He was born in 1898 and adopted the same year. Is it a possibility to find a document stating a legal name change?

Thank you

I've seen several name changes in the margins of the birth certificate from the registry office.
You can also search Parts B and C at the end of each year. In those parts, records of births under more or less special circumstances were recorded.
For example, I remember that a woman had abandoned her child as foundling. That child was registered as such in the civil registry. The mother regretted it after a few days and had a deed drawn up at the notary in which she stated that she was the mother. Subsequently, a completely new birth certificate was drawn up in part C of that volume.
Check out the entire year of civil status. My experience is that the registration was pretty perfect, at least in the area where I am researching. So there should be something to find

Are you sure he was formally adopted? If there is no notation on the birth record then it is most likely he was fostered and on arrival in America assumed their family surname since the rules were much more relaxed than in Italy.

If a foundling, having fantasy surname by civil records officer, it is legally adopted from a couple, well the foundling lose his initial identity, first name and surname at birth, and assuming the new identity, new first name and surname of stepfather.

I don't know whether or not he was. He was taken in by his wet nurse at the foundling home, and took their family name.

He could not have 'taken' their family name without the father or mother formally 'recognising' him as their child. This would be noted on the birth record. If he took their surname after they arrived in America this is another story since in America you can be known by any name as long as its not for fraudulent purposes.
The ship manifest will tell you. His travel papers would have been issued in his 'original' or 'recognized' surname.
