Hello Regina, I have searched high and and low and was unable to find a physician named Bernardo Nunez de Villavicencio that would had been an adult at the turn of the century. There is a Dr. Emiliano Nunez de Villavicencio y Alvarez born in Havana in 1845. He married Adolfina Palomino y Dominguez 1868 and their children were Amparo, Adelina, Maria Luisa, Adolfo(1882), Raul, Federico, Armando and Enrique (1872) Nunez de Villavicencio y Palomino. Raul's in-law's were Eduardo Adot and Eloisa Rabell y Elzaurdy. Enrique was a a doctor as well. If you can get your hands on your great-great grandfather's death certificate or your great grandmother's baptissmal certificate, it might show Bernardo's full name as well as his mother's name for some greater insight. Good Luck, Tony
