Miranda proved an astute businesswoman, earning the respect of her peers. Her decision to leave her husband was unusual at the time but she was able to secure support, including that of the Bishop of Santa Barbara. She was also able to retain all of her land after California became a state in 1850. The federal government required all landowners to verity their ownership. Though she was illiterate, she was wise enough to keep all of her property records and hired trustworthy people to represent her. In this way she retained her land; other landowners were not so lucky.
Miranda is so highly regarded among the early settlers of the area that today there is a school and a park in Palo Alto named in her memory.
