Origin
Meaning and origin of Moix
The surname MOIX has its origins in Catalonia, a region in northeastern Spain. It emerged in the early 13th century from the Catalan word 'moix', which means 'cat'. This suggests that the name may have originally been a descriptive nickname given to someone with feline-like qualities or who had a fondness for cats.
One of the earliest recorded instances of the MOIX surname can be found in the medieval tax records of Barcelona from the year 1284, where a certain Bernat Moix is listed as a taxpayer. This indicates that the name was already well-established in the region by that time.
During the 14th century, the MOIX surname began appearing in various legal documents and municipal records across Catalonia, particularly in the coastal areas and the city of Barcelona. This was a period of economic growth and urban development in the region, which may have contributed to the spread and consolidation of the surname.
In the 15th century, a notable figure bearing the MOIX surname was Jaume Moix, a renowned architect and sculptor from Barcelona. He is credited with designing several notable buildings in the city, including the Gothic-style Salo del Tinell within the Palace of the Kings of Aragon.
Another influential individual with the MOIX surname was Joan Moix, a Catalan writer and philosopher who lived in the late 16th and early 17th centuries. He is best known for his work "Discurs sobre la vida humana", a philosophical treatise exploring the nature of human existence and virtue.
During the 17th century, the MOIX surname can be found in various parts of Spain, suggesting that bearers of the name had begun to migrate and settle in other regions. For example, records from the city of Seville mention a certain Miguel Moix, a merchant who was active in the silk trade.
In the 19th century, a notable figure with the MOIX surname was Josep Moix i Regàs, a Catalan painter and art teacher. He was born in 1835 and is known for his landscapes and genre scenes depicting rural life in Catalonia.
Another individual of note was Francesc Moix, a Catalan journalist and writer who lived from 1938 to 2003. He wrote several novels, short stories, and essays, often exploring themes related to Catalan identity and culture.
These are just a few examples of the individuals bearing the MOIX surname who have left their mark throughout history. While the name may have originated from a humble descriptive nickname, it has since been carried by notable figures across various fields, reflecting the rich cultural heritage of Catalonia and Spain.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. 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.
