I'm researching for the background of my great grandfather Modesto Rocha. He arrived to Bolivia possibly around 1920's-30's forming a very strong family line in a town called Arbieto, in Cochabamba, Bolivia.
There is nothing known about his background/past prior to arriving to the small town Arbieto, but after research I've discovered it possibly comes from Portugal. Maybe he immigrated from Portugal, maybe his parents did or something.
I'd appreciate if any one knows any information on him or even the last name Rocha immigrating to Bolivia in the 1800s and/or 1900's.
