Her watercolor sketch of the Alamo, completed during her first residence in San Antonio, is one of the earliest-known depictions after the battle. Although she did not herself immigrate to Texas until two years after the fall of the Alamo, in 1889 she wrote a brief account of the battle based on the recollections of witnesses. She died on February 24, 1898, and was buried beside her husband at San Antonio City Cemetery Number 1.
