My great-great grandfather was Sicinio Vizcarrondo Mongran, who lived in Rio Grande (1910) and Carolina (1920), Puerto Rico. My grandmother had told me that he was a doctor and his name was "Sicinio" (even though it's spelled differently on the 1910& 1920 census) I would appreciate it if anyone can give me any information about his parents and other ancestors, and if he was related to Lorenzo Vizcarrondo Mongran and/or Lorenzo Vizcarrondo Ortiz de Zarate. Thank you.
