About Jacinta Rafaela
Jacinta Rafaela was a Chinese mestiza. She is believed to be the daughter of a Christian Chinese and a Chinese mestiza. The "Rafaela" part of her name was very likely added in adulthood, in honor of the patron of the Parian settlement, San Rafael, just as Domingo, at his marriage, added Antonio to his name.
