Livermore worked for a time at Mission San Gabriel and then moved north, working as the mayordomo (ranch foreman) at Rancho Bolsa del Potrero y Moro Cojo of Joaquín de la Torre, near Castroville. On 20 June 1823, Robert was baptized at the Mission Santa Clara into the Catholic faith, given the name Juan Bautista Roberto y José. At about the same time, in Monterey, he requested and was given permission by Governor Pablo Vicente de Solá to remain in California.
