I'm sure you have got relatives here, in Barcelona, because there are about 10 families in the city, but I don't know any of them. My family comes from Sitges, a village near from Barcelona, and we have been in Catalonia since 1700 (and before...). Some relatives emigrated to America, but I think they didn't return, I don't know. If I meet somebody that could be your relative, I will tell him about this internet place, sure! One question: do you know Emiliano Gorgas? He's in the page, he was born in Puerto Rico and now he lives in El Paso, Texas. Maybe he knows something about your family.
