What my sister, Linda, has uncovered, however, it's my mom's side

What my sister, Linda, has uncovered
My mom was born in barrio Babasit, Manaoag, Pangasinan and my dad from Ordaneta City, Pangasinan. My dad was born Irenio Jaime Bernal Almoite and changed his name to Jaime Bernal in Boston, Massachusetts in 1946. Felicidad's(my mom's) dad was Paulino Mangonon who married Alejandra Ligaspe and Paulino's dad was Silvestine Mangonon who married his 2nd wife Tomasa Pascua in 1870. What's fascinating is that Tomasa's dad was Acedo Pascua who married Leonarda Mangonon!! There's that Mangonon again. But Alejandra's parents were Jacinto Ligaspe and Filomena Doriches(spelling?) and her dad Jacinto's parents were Salvador Ligaspe and Rafaela Pascua!! And there's that Pascua again.

Two questions of note: (1)Who was Silvestine's first wife? And (2)who were his parents?

That being said, I am looking for genealogy on my father's side. Since his original name and birth is different, that is where I shall start. With his original name and the town of his birth. I must first say, we were under the immpression that his birth town was spelled starting with an "O" instead of a "U". I am glad I discovered this in my original Google search. Also, within that search, I discovered his point of entry into the United States, and the bit about his name change in the city of Boston, Massachusetts.

So now, let us begin...
