 According to Felix Huerta, a 19th-century Franciscan scholar and missionary, the original inhabitants of Namayan trace their roots to a ruler named Lacantagcan/Lakan Tagkan and his wife Bouan/Buwan ("moon"), who were said to have resided in this village.Other territories that belonged to the dominions of Lakan Tagkan and Buwan included the modern Manila districts of Malate, Paco, Pandacan, Quiapo, Sampaloc and San Miguel; the cities of Pasay, San Juan, Mandaluyong and Makati; and the municipality of Taytay in Rizal Province.The Spaniards established settlements in Santa Ana that served as the seat of Namayan, with the area awarded to the Franciscan missionaries.
