Origin
Meaning and origin of Casler
The surname Casler has its origins in Germany, with the earliest records dating back to the 16th century. It is believed to have derived from the German word "Kasler," which referred to a person from the town of Kassel in the state of Hesse.
In the early 1600s, the name appears in various church records and town registers in the Kassel region. One of the earliest documented examples is Johann Casler, born in 1612 in the village of Oberkaufungen, near Kassel.
The name's spelling has evolved over time, with variations such as Kassler, Casler, and Kasseler appearing in historical records. Some of these variations may have been influenced by the names of nearby towns or regions.
During the 17th and 18th centuries, as German emigration to America increased, the Casler surname began to appear in colonial records. One of the earliest known instances is Joachim Casler, who arrived in Pennsylvania in 1753 from the Rhineland-Palatinate region of Germany.
Notable individuals with the Casler surname include Johann Casler (1765-1842), a prominent German clockmaker and inventor from Nuremberg, and Friedrich Casler (1806-1879), a German-American artist and lithographer who settled in New York City in the 1840s.
In the United States, the name Casler gained prominence in the 19th century. Benjamin Casler (1816-1892) was a successful businessman and politician from New York, serving as a member of the state legislature. Hiram Casler (1828-1903), born in Pennsylvania, was a Union Army officer during the American Civil War and later served as a judge in Ohio.
Another notable figure was John Casler (1847-1923), a prominent architect from Ohio who designed several notable buildings, including the Cuyahoga County Courthouse in Cleveland.
While the Casler surname is not among the most common in the world, it has left its mark in various fields throughout history, with its roots firmly planted in the German regions of Kassel and the surrounding areas.

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 Casler surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Casler (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
