Malinalli

Malinalli was theorized to be the birthname of the Nahua interpreter Malinche.

Apologies for the Wiki quote, although this has got other literary sources linked in the article but: "Malinche was baptized in the Roman Catholic Church and given the Christian name "Marina",[7][18] often preceded by the honorific doña.[19][20] Since at least the 19th century,[13] she was believed to have originally been named Malinalli[b], (Nahuatl for "grass"), after the day sign on which she was supposedly born.[23] Accordingly, Marina was chosen as her baptismal name because of its phonetic similarity.[21] Modern historians have rejected such mythic suggestions,[7][13] noting that the Nahua associate the day sign Malinalli with bad or "evil" connotations,[7][23][24] and they are known to avoid using such day signs as personal names. Moreover, there would be little reason for the Spaniards to ask the natives what their names were before they were christened with new names after Catholic saints.[26]" (https://en.wikipedia.org/wiki/La_Malinche)

So therefore, Malinalli is unlikely to have been the birth name of La Malinche. Moreover, Malinalli was historically unlikely to be used (if at all) as a name by Aztec or Nahua people as it was historically seen as an evil omen.
