Looking for info on Corso family in Ribera.

My gg-grandmother was Carmello Corso. My g-grandmother was Archangela/Angelina Corso Mumphrey. Angelina came with her mother and sister to N.Y. and then came to Baton Rouge,Louisiana.

On the ship's manifest, there was listed an Emmanuelle Corso also from Ribera. I don't know if this is the same family.

Any info pertaining to these individuals would be greatly appreciated. I can find absolutely no info on them.
