Welcome to this forum.
I found this information below from the web site.. 188.8.131.52/ascs_web...heda.faces
I could not find Achille in the above web site.
After looking at the 1912 manifest you speak of, Achille is leaving his father, Tommaso in Bianchi.
SIAS Code IT-ASCS-F680258
Ufficio Leva della Provincia di Cosenza, Enlistment year 1887.Volume number 226,
document number 125 page 310 section b
Francesco Antonio Abate, contadino enlisted on --/--/----
born on 27/01/1887 to BIANCHI
son/daughter of Tommaso Abate and of Caterina Arcuri
This Francesco could be the brother of your Achille. I believe the manifest below is Francesco and he is leaving his father, Tommaso to visit his brother, Achille. He is from Bianchi and on line 9.

My suggestion is to go to a Family History Center near you and rent the records on film for Bianchi. You may now know the mother and father of Achille, but you need to verify it.
There are several researchers on this forum researching in Cosenza and they may possibly add to this thread.
Hope this helps,
