Origin
Meaning and origin of Chumacero
The surname Chumacero is a Spanish name that originated in Spain. It is believed to have been derived from the word "chumacera," which refers to a bearing or bushing used in machinery and equipment. The name likely originated as an occupational surname for someone who worked with or manufactured these types of bearings.
One of the earliest recorded instances of the Chumacero surname can be traced back to the 16th century in the region of Andalusia, Spain. In particular, there are records of a family by the name of Chumacero residing in the city of Seville during this time period.
While the name does not appear in notable historical records such as the Domesday Book, there are some references to individuals with the Chumacero surname in various Spanish archives and documents from the 16th to 18th centuries. For example, Juan Chumacero, a merchant from Seville, is mentioned in trade records from the early 17th century.
As the Spanish Empire expanded in the Americas, the Chumacero surname began to appear in various colonial records. One notable example is Pedro Chumacero, a Spanish soldier and explorer who participated in the conquest of Peru in the 16th century.
In the 18th century, there was a prominent Chumacero family in the city of Cadiz, Spain. One member of this family, Francisco Chumacero (1707-1782), was a renowned naval officer and engineer who contributed significantly to the development of the Spanish Navy.
Another individual of note was Miguel Chumacero (1836-1914), a Mexican poet and diplomat who served as the Mexican ambassador to various countries, including Spain and France.
During the 20th century, the Chumacero surname gained recognition in the literary world with the Mexican poet Alí Chumacero (1918-2010), who was considered one of the most influential poets of his generation in Mexico.
While the Chumacero name can be found in various Spanish-speaking countries today, its origins can be traced back to Spain, where it likely began as an occupational surname related to the manufacturing of bearings or bushings.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers.
