Father Vicente Francisco Sarría stayed on in poverty, faithfully served the Indians until his death in 1835. Secularized in 1835, the mission was regranted to the Bishop of Monterey in 1859. In ruins after 1874, the chapel was reconstructed and dedicated under the auspices of the Native Daughters of the Golden West, October 9, 1955.
