It has not been possible to clarify whether the word Tasquillo is of origin Otomí or Nahuatl.

Tasquillo was populated by a few ethnic groups which were the Nahuas, Toltecs and especially the Otomí groups who have given the name “Mashei ” to the place. Among the most important historical events are the discoveries of curious junk, metals, carved stones or sticks and tools of men who were buried in clay pots. It is said that these relics are found in the Huemac.

in the 15th century under the domination of the Mexica culture it was named Taxco. Later, with the Spanish conquest in the 16th century, it was given the name “town of the natives of San Bernardino,” subject to a commission from the Marquis of Zúñiga. and during this time the Spaniards settled at a point called Donijá, which is located southeast of the main square.

in the 17th century it was given the name of Taxquillo, a word composed from Nahuatl or Otomi. In Nahuatl the word comes from the game of tlachtli which means "ball game", In its Otomi dialect the meaning would be "Place of Goats", in Spanish the word of illo means diminutive or small, which gives it another meaning "Small place of the game of ball" or "Small place of goats".

According to what is known by the mayoralties, in the 18th century it was not considered among the towns to citizens due to its lack of importance and poverty-rate, since it was simply a neighborhood and municipal seat of the town-hall of Ixmiquilpan.
