Jody Ann,
I just came across your post today while doing a Google search on Lercara.
My family on both sides is from Lercara. There is a Sferlazza in my line and a Raia.
My great-great-grandfather on my mother's side married Francesca Sferlazza. She was born around 1823 and died 1/25/1903. I have a copy of her death record. Her father was Giuseppe Sferlazza and her mother was Maria Ex Ignotis. If you are related to her, I would be happy to email you what I have.
Regarding the Raias, my great-grandmother on my father's side married Giachino Raia. He died and she got remarried to my great-grandfather. So, I'm not a blood relation to him. I have a copy of their marriage record (10/28/1875)
There are a lot of Raias in the records I have seen from Lercara, but not as many Sferlazzas. Perhaps we are related.
Good luck and ciao!
Michael
