I noticed you wrote your surname with 2-Ps. I would like to know more about your Grandpa. Where and when was he born? Who he married? Do you know the names of Antonio's children?
My Second Great Grandpa is also named Antonio Capella who married Lorenza Oliver on the year 1844 at the Parochial Church of San Carlos Borromeo in the "Loyal Ville of Aguadilla - Province of Porto Rico". That was when Puerto Rico was still a province of Spain. They had 7 children named: María, Petrona, Estervina, Elias, Antonio, Francisco, and Justina.
