Solved! A researcher in Italy explained to me that it did say "Furbia," and: The correct name is Fulvia. The form "Furbia" is dialectical. The "Furbia" form is also typical of Acri's speech. Thanks to all who commented.

Thank you both. I have been searching for years and will keep trying.

This is the portion of a document from 1844, Santa Sofia d'Epiro, Cosenza, Calabria. On the last line, I can't make out the first name, which looks like Furbia. Thanks for any help.
