The residents of Santa Maria chose the Virgin Mary as the namesake of their town and Saint Sebastian as a minor patron saint. The settlement and its surroundings became quite appealing to ranchers; by 1600 around 20,000 head of cattle were active in the Lagos valley, facilitating the eventual creation of the charreria-style rodeo. The increasing population of the area contributed to the naming of the first ordinary Mayor of Santa Maria de los Lagos, the miner Pedro Marfil from Guanajuato. Marfil would be succeeded by Gonzalo Vazquez Baladez, the first and only clergyman to-date to serve as mayor of the town.
