Why would an accent occur after an Italian surname?

I would like very much to access to your tree. Many thanks.

I've only just today seen your post.
I'm sitting in a hotel waiting for my wife so I don't have my genealogy database with me. The family rumor is that the Cina' family is from Switzerland or northern Italy. Can you confirm or deny this rumor?

This is indeed the correct Arcario Family. Father: Joseph (Giuseppe) b. 1862, Caltabellotta. Would like any information about his father, uncles, etc. Many, many. Thanks.
Any information about Rinaldi family (Teresa, b. 1868) in Ribera.

Great. This is the correct family. I've got to digest and see what duplicates what. Thanks so much. I'll be back.

Looking for information on Vincenzo (Vincent) Arcario, b. Sicily, maybe Ribera, ca. 1891, or his wife (and families).
Married Antoinetta (Antonina) Cina, b. Sicily ca. 1898.
Father of Vicenzo may have been Giuseppe (Joseph).

Brother of Vincenza may have been Mariano (Maurice) b. 1886.
