Marquita is a feminine given name with roots in the Spanish and Portuguese languages. It is derived from the ancient Roman name Marcia, which itself originated from the Roman family name Marcius. The name Marcia was borne by several notable Roman women, including Marcia, the wife of the Roman general Cato the Younger.

The name Marquita emerged as a diminutive form of Marcia, with the addition of the Spanish and Portuguese diminutive suffix "-ita". This suffix was commonly used to create affectionate or endearing versions of names, often indicating smallness or youthfulness.

One of the earliest recorded instances of the name Marquita can be found in the 16th century, when it appeared in various Spanish and Portuguese records. During this time, the name was primarily confined to the Iberian Peninsula and the Spanish and Portuguese colonies in the Americas.

Throughout history, several notable individuals have borne the name Marquita. One of the earliest was Marquita Tenorio (1522-1589), a Spanish noblewoman and lady-in-waiting to Queen Isabella of Portugal. Another early bearer of the name was Marquita de Guzmán (1555-1628), a Spanish nun and mystic who founded the Order of the Conception of Our Lady.

In the 19th century, Marquita Fernández (1820-1892) was a Cuban poet and writer who was part of the literary movement known as the "Romantics of Havana". She was renowned for her lyrical poetry and her contributions to the development of Cuban literature.

Marquita Pring (1884-1964) was an American artist and illustrator who was particularly known for her illustrations in children's books. Her work appeared in publications such as St. Nicholas Magazine and The Delineator.

Marquita Plachetka (1917-2005) was a German-born American mezzo-soprano who had a distinguished career in opera and concert performances. She was particularly acclaimed for her interpretations of the works of Richard Wagner.

While the name Marquita has seen some use throughout history, it has never been among the most popular given names. However, its origins and historical references reflect the rich cultural heritage of the Spanish and Portuguese-speaking worlds, where the name has its deepest roots.
