The Italian civil records are quite good often dating from the early 1800s, and easy to use. They are in Italian, of course. The earlier records tend to be completely handwritten, with the later ones being forms with the data written in, these are a bit easier. The earlier birth records will say when, and usually where, the child was baptized thus providing a link to the church records, only some of which are online. family Search says the following about their records from Tuscany:
Civil registration (stato civile) of births, marriages, and deaths within the custody of the State Archive of Firenze (Archivio di Stato di Firenze). Includes supplemental documents (allegati); annotations (annotazioni); baptismal records (battesimi); residency records (cittadinanze); declarations of death (dichiarazioni di morte); ten-year indexes (indici decennali); inventories (inventari); births and deaths of non-Tuscans (nati e morti di non Toscani); foreign births and deaths (nati e morti all’estero); and marriage banns (pubblicazioni);. For the most part, this collection contains records for the modern region of Tuscany (Toscana). Additional smaller portions of the collection are for the modern regions of Emilia-Romagna, Liguria, and Umbria. The provinces represented in the collection include the following: Arezzo, Firenze, Forlì-Cesena, Grosseto, La Spezia, Livorno, Lucca, Massa e Carrara, Perugia, Pisa, Pistoia, Prato, and Siena. Availability of records is largely dependent on time period and locality. Images for this collection were mistakenly made available to the general public who registered on this site. Because of the agreement signed 30 June 2011, the publication rights of images belongs to the Italian National Archives (DGA) who publishes them freely to all on their Portale degli antenati: http://www.antenati.san.beniculturali.it/.
The church records, if you can find them online, may go back to the 1500s for the larger churches, sometimes even earlier. These records are in Latin. They are often indexed, especially in the larger churches.
