Origin
Meaning and origin of Izlar
The surname Izlar is believed to have originated in Spain during the medieval period. It is thought to be derived from the Old Spanish word "isla," which means "island." This suggests that the name may have been initially given to someone who lived on an island or came from an island.
One of the earliest recorded instances of the name Izlar can be found in a manuscript from the 14th century, which mentions a man named Juan Izlar who was a prominent landowner in the region of Andalusia. This suggests that the name had already been established in Spain by this time.
In the 16th century, there are records of an Izlar family living in the town of Seville. One notable member of this family was Diego Izlar, who was born in 1542 and served as a magistrate in the city. His son, Francisco Izlar, born in 1578, was a renowned scholar and author of several books on philosophy and theology.
The name Izlar also appears in documents from the 17th century, including records of a nobleman named Álvaro Izlar, who was born in 1632 and held significant landholdings in the region of Catalonia. Another notable figure from this period was Juana Izlar, born in 1654, who was a prominent artist and painter known for her religious works.
In the 18th century, the Izlar name was associated with a family of merchants and traders based in the city of Cádiz. One member of this family, Pedro Izlar, born in 1712, was a successful businessman who established trade routes with the Americas and amassed a considerable fortune.
Throughout the 19th century, the Izlar name continued to be found in various parts of Spain, with several individuals achieving notable positions in society. One example is Manuel Izlar, born in 1842, who was a respected lawyer and judge in Madrid.
While the surname Izlar is relatively uncommon today, it has a rich history that spans several centuries and is deeply rooted in the cultural and linguistic traditions of Spain. The name's origins can be traced back to the medieval period, and it has been borne by individuals from various walks of life, including landowners, scholars, artists, merchants, and legal professionals.

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.
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. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Izlar surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
