Today I've found news about Taravella, and I'm almost sure that they are "your" Taravella (there are some things very similar and some others different).
I know a Margherita Taravella (n. 1844 in Rocconi) who married Lazzaro Quagliaroli (n. 8 april 1835 in Rocconi).
They married about in 1878 in Rocconi.
The 23 june 1878 they have Domenico Giacomo Quagliaroli borned in Rocconi. He died the 17 july 1954 in Ferriere.
D.G. Quagliaroli married Maria Taravella the 27 juin of 1907 in Rocca, near Ferriere (not far from Rocconi).
This Domenico Giacomo, I think, was the Domenico named by Sylvain, his grandfather… Also in my records he married Maria Taravella.
If the father of Luigi was Lazzaro, Domenico and Luigi were brothers and Maria was his sister-in-law.
In my records I don’t found Luigi or other brothers (I understand they are Antonio and Andrea thanks to your post), only Domenico Giacomo, but I know that my file isn’t complete.
Maria Taravella was born in 1876 in Rocca near Ferriere from Francesca Mutti (n. abt. 1853), and Marco Taravella (n. abt. 1845), both from Rocca of Ferriere. They married abt. 1875.
I haven't found brothers or sisters (but I know that the file isn't complete).
Here there are the other things I know:
Lazzaro Quagliaroli's father was Giacomo Quagliaroli (n. 1805 in Rocconi) and mother was Elisabetta Cagnolari (n. about 1810 in Rocconi). Lazzaro had two brothers and one sister: Giovanni, Giuseppe and Maria Angela.
Giuseppe was born in Rocca the 6 feb. 1829
Giovanni was born (maybe) in Rocca the 3 apr. 1830 – the records about 1830 are missing.
Maria Angela was born in Rocca the 8 june 1832. – In this document there is written that ”Elisabetta Cagnolari of property owners Rompeggio”. Rompeggio is a village near Rocconi and Ferriere.
Lazzaro was the last son. He born in Rocconi the 8 apr. 1835.
The grandfather of Lazzaro was Simone Quagliaroli (born in Piacenza city abt. 1778). He lived in Retorto, near Ferriere, from about 1800 to 1838. He died the 19 june 1838. He married about in 1804 at Retorto Artensia Farinotti (abt. 1783 in Retorto) and he had two children: Giacomo (Lazzaro’s father) and Marco, born in 1815 in Retorto.
I think this Marco is the Marco know by Sylvain ^_^
In my records there is a written: COMPARSO: Son, Marco 23 and Vicino Giovanni Sattani 31 of Retorto.
I think “Vicino” is not a owner name but is the word for “neighbour”.
The great grandfather of Lazzaro was Pietro Quagliaroli (born about in 1748 in Piacenza and died before 1837 in Retorto). He married in 1777 at Piacenza Teresa Boscani (born about in 1753 in Piacenza and died before 1835 in Retorto) and they had Simone.
This is all I have. All these information are from “Ferriere Stato civile Archive 1806-1929”)
