Historical Overview

Founded in 1772 from lands originally under San Juan's jurisdiction, Bayamón grew from a network of sugar ingenios into one of Puerto Rico's most populous municipalities. Known as the 'Ciudad del Chicharrón,' it anchors the metropolitan area and served as the mother town for three daughter municipalities: Guaynabo, Comerío, and Cataño. Parish records at La Invención de la Santa Cruz date to 1772, and civil registration began in 1885. Because families frequently crossed between Bayamón, San Juan, and its daughter towns, researchers should also search neighboring parishes and metropolitan-area civil registries.

Coat of Arms

The Bayamón coat of arms features a cross at center representing the Invención de la Santa Cruz, the town's patron. Blue and silver waves across the lower field represent the Bayamón River. A sugar mill recalls the early ingenios that drove the town's founding and economic life. Green fields symbolize the agricultural fertility that made Bayamón's separation from San Juan viable.
