Raised by Pedro Chavez but was an illegitimate son of Tomé Dominguez. Unlike some researchers I have placed Francisco as an illegitimate son of Tome III because Tome IV was definitely dead by 1681. Francisco de Chavez birth date is not known but he was most likely born after 1680. In the 1730 baptism record of his son Joseph Felix he went by the name Francisco Xavier Domínguez. In 1745 Parral, Francisco de Chaves was the main witness at the marriage of Francisco Baca, son of Estefania Dominguez de Mendoza - daughter of Francisco Dominguez de Mendoza, which supports the claim of a family connection to the Domínguez clan.
