[1] On January 24, 1830, Francisca Carrillo met a young soldier named Mariano Guadalupe Vallejo who arrived in San Diego in the wake of the Solis revolt.

Echeandía gave a toast at the reception, during which he said of Carrillo: "I have known his young wife since she was eight years old, and I have had repeated occasions to admire her fine manners.

On May 1, 1834, Governor José Figueroa assigned Vallejo the task of establishing a fort in the area, north of San Francisco, that would eventually become Sonoma County.

[2] Carrillo had a third child with Vallejo shortly after arriving in Sonoma: a girl named Epifania Gertrudis, born on August 4, 1835.

[7] Carrillo was at Casa Grande when the Bear Flag Rebellion happened in 1846, resulting in the capture of Sonoma by American immigrants for 25 days and the imprisonment of Jacob P. Leese and Vallejo.

During the rebellion, Carrillo's brother, Ramón, was accused of joining Juan Nepomuceno Padilla in killing two Bears, Thomas Cowie and George Fowler.

Carrillo smuggled weapons to Ramón, Padilla, and her mother (who lived just north of Sonoma as owner of the rancho of Santa Rosa, California).

Ramón denied having anything to do with the death of the Americans and gave a sworn affidavit saying Padilla directed the killing of the men.

Carrillo celebrated the raising of the American flag, writing a letter to Vallejo, who remained imprisoned at Sutter's Fort.

Both Carrillo and Leese resented the fact that certain Bears, including William Ide and Robert B. Semple, continued to spend time in Sonoma so soon after the Navy quelled the takeover.

"[9] She lamented that if the United States Navy would have arrived sooner - in mid-June - the unnecessary deaths of numerous people, including Cowie and Fowler, would have never happened.

[11] In May 1847, Vallejo gave Semple and Thomas O. Larkin a five square mile land tract, which would become Benicia, California.

It was at Lachryma Montis where Carrillo threw grand parties, including entertaining David Glasgow Farragut, William T. Sherman, Ulysses S. Grant and Edwin Bryant.

[7] As the Vallejo's wealth diminished, in the 1860s they began growing and selling figs, apples and grapes, and raising chickens for eggs.

[15][16] Carrillo oversaw the distribution of produce and eggs to San Francisco and throughout Sonoma, selling at bakeries, restaurants and hotels.

Edwin Bryant called Carrillo "a lady of charming personal appearance" who had "the highest degree that natural grace, ease, and warmth of manner.
