The first Babilonia in Puerto Rico arrived from Mallorca, Balearic Islands off the coast of Spain sometime in the 1760s. Capitan Miguel Babilonia Polanco was born to Juan Amador Babilonia and Chatarina Polanco in 1743. His first marriage was to Maria Mendez (1741-9 Aug 1796) with whom he had 12 children. After she died, he married his wife's cousin, Benita Lorenzo de Acevedo y Gonzalez (1781-10 May 1861), and had 7 more children. By the time of his second marriage in 1797, both of his parents had already passed.
I've been investigating this line since the late 1990s, and have been involved with genealogy since then. Perhaps I should say, obsessed?
