I am a Placensia descendent (now spelled Plaisance). I descend from Juan Placensia and I will be glad to share what information I have on this family. I don't check in here very often but will check for any word from you.
Hello, I remember entering the Puerto Rican Genelogy Society hompage sometime ago and the president of the Puertorican Genelogical Society is Placensia too. I believe they have gathered all about their last name < Placensia > in Puerto Rico. Good Luck.
