In looking at the birth record, I don't think I have Antonino's mother's maiden name correct.
The birth record is dated on Sept 25, 1870 at 9 a.m. in the town hall.
Appeared Giuseppe Mento of Leone, age 27, a farmhand living in Villaggio Pelligrino di ? of this town. (I don't see a hamlet or frazione of this town with this name).
He presented a male infant born to his wife on the 24th at 8 P.M. His wife's name Maria Giuseppa Gxxxx of Padre Ignoto. She was of an unknown father. She was living with him in the house of their own habitation in this village.
That's definitely what you need to do. I think the birth record above is much clearer than the marriage record concerning the surname of the mother, but it would be good to get another record to confirm which surname is the correct one.
