I have found in my research several lineages where the maternal names survived for up to three generations. In some cases it was because the father did not have a surname (i.e. was indigenous) and thus the maternal one was given to the child by default. In such cases, the husband sometimes appears with his wife's name as well.

Iin other cases it appears to be that the maternal side had the land and prestige and was perhaps lacking of male heirs so the children took on the mother's name in order to propagate that name.

Then there is a peculiar tradition of naming women after grandmothers whereby they are given the entire name so if the grandmother was named Maria Saucedo, the mother was named Ana Ortiz and the father Lorenzo Miramontes, the daugher would be named not Maria Miramontes and not even Maria Ortiz, but Maria Saucedo just like her grandmother, thus she would carry her mother's mother's maiden name.

The term maiden name in Latin America is somewhat redundant because women don't really change their names, thus they have a name in their maiden lives that remains their name in their married lives. In modern times the practice of attaching a "de" husdband's name after their own has become commonplace, but that is not considered the woman's name.
