Need help with the Mingoia side of my family

[Misswinz77]

I have made quite some progress on every side of my family tree (going back to early/mid 1700's) except for the Mingoia side. I am still stuck at Samuel (Salvator) Mingoia b. 1874 and Antonina DiDomenica/Domingo b. 1875. They are my Great-Great Grandparents. They immigrated to the USA between 1913 and 1915 from Villalba, Caltanissetta, Sicily. They had 3 sons, all born in Sicily. Anthony, Gaspare and Samuel (Salvadore born 1902). Salvadore grew up and married Anna Butera.

On the census reports, Sam switched back and forth between Sam and Salvator. And Antonina switched back and forth between Antonina and Nina.
