Yes, I'm still following up on it. You should check out the books written by Alberto Osorio Osorio. See worldcat holdings:http://www.worldcat.org/identities/lccn-n90-603868
I'm looking for Jose Eustacio Osorio, had a daughter named Josefa Osorio De Leon and a grandson, Jose Rosario Garrido Osorio (born about 1860). I'd like to find out if any of them emigrated to Panama from Curacao.
