The Rizal surname was obtained by Francisco Mercado as suggested to him by a provincial governor after the Governor General of the Philippines, Narciso Claveria, issued a decree in 1849 by which native Filipino and immigrant families were to adopt Spanish surnames from a list of Spanish family names. Jose Rizal also obtained the surname Rizal after dropping three other names that made up his full name. Jose Rizal also retained Protacio as his other family name. His family never actually recognized his Rizal surname but Jose Rizal was forced to use it so that he can travel freely and disassociate him from his brother who was known to be notorious due to Paciano’s links with native priests who were executed after they were found to be subversives.
