I, unfortunately, do not have too much on my Ferrantelli line. What I do have will be presented here with additions as I receive them.
I will begin with my grandmother, Rosa Coraci:

Rosa Coraci  b. 11 April 1898 in Alcamo, Sicily  was the daughter of Tomaso Coraci  b. abt 1862 in Alcamo, Sicily'  -  d. abt 1930, and Giuseppa Ferrantelli  b. 2 June 1869 in Alcamo, Sicily. The two were wed on 3 Oct 1885.
Giuseppa was the daughter of Gaetano Ferrantelli  b. ca 1839 in Alcamo, Sicily -  d. 10 July 1885, and Rosa Milano  b. abt 1845 in Alcamo, Sicily  -  d. bef 1885. I am not sure when  Gaetano and Rosa were married, but I do know that Giuseppa was an orphan by the time she wed Tomaso.
Gaetano was the son of Giuseppe Ferrantelli, and that’s as far as I am with this line.
A foot note - Rosa Milano’s father was Pietro Milano.
