Pujo is Maria's father's nickname, not her last name. Curators shouldn't be posting incorrect and undocumented information.
If this is his nickname as you say it, then it should stay in AKA field not in the first name.
I found it it in the books for Doli as a family name.
Can we get more details about the book and possibly a screenshot of the page, please?
Croatian communists also introduced a habit of writing person's nickname after their last name, which doesn't make it a last name.
Yes, Croatian communists were very active 200 years ago
