In ancient times, the Tagalogs had a naming system that changed via family dynamics. A Tagalog man (especially a chief) would lose his name, take his first born's name, and become known as "son's/daughter's father"; rather than his offspring adopting his surname like today. If he was baptized into Christianity, he would take a Spanish "Christian name" but retain his native name as surname. For example, Calao's father became Don Luis Amanicalao (Lord Luis, a chief of Tondo, Calao's Father). This also applied to mothers (e.g., Inanicao) etc. One also gained numerous "poetic" titles (i.e., "pamagat"; lit. "to have something to go before", today literally translated as "title", from where the prenom "Gat" is derived) from his renown/actions (e.g. valiance in battle) or other naming means (like a naming feast for those without offspring).
