My grandfather, Angelo Roberto DiNardo, was born in 1888. His father was Raffaele DiNardo (b. 1858), and his mother was Filomena DiNardo (DiNardo was her maiden name). Angelo Roberto had a brother Luigi(!) and a brother Paolantonio.
Raffaele had another marriage, to Angelantonia DiNardo (yes, another DiNardo maiden name. I think Filomena and Angelantonia were sisters). Raffaele and Angelantonia had a son, Antonio, and a daughter, Annina.
Pretty confusing, no?
My grandfather settled in Aliquippa, Pennsylvania, which is very near McKees Rocks, just a few miles away along the river. I also grew up in that area.
Let me know if this rings any bells with your mother!
