Duhaylungsod

Hello!

My name is Svein and I am trying to find out more about my wifes family three.

My mother in law is born Duhaylungsod and the family is coming from Oroquita and Siqihour.

What I know is that my wifes great grandfather was Francisco Duhaylungsod, the grandfather Severiono Duhaylungsod and he got 5 kids;

The names are Nena, Agapito, Vicente, Pabianito and Basillio Duhaylungsod. Is there any archives I can search to know more?

Best Regards

Svein Egil Sørland
