Origin
Meaning and origin of Izatt
The surname IZATT originated in Scotland during the medieval period. It is believed to be derived from the Old English words "ise" meaning iron and "hatte" meaning hat or helmet, suggesting the name may have originally referred to an ironsmith or someone who made iron helmets or headgear.
One of the earliest recorded instances of the name can be found in the Ragman Rolls of 1296, which list Scottish landowners who swore fealty to King Edward I of England. The name appears as "Isat" in this document, indicating the surname's early spelling variations.
The IZATT surname is particularly concentrated in the areas of Angus and Perthshire in eastern Scotland. It is possible that the name may have originated in these regions, where iron mining and metalworking were prevalent industries during the Middle Ages.
In the 16th century, the IZATT name appears in several Scottish parish records, such as the baptism of Johne Isatt in Perth in 1565 and the marriage of David Isatt and Jonet Ramsay in Arbroath in 1589.
One notable early bearer of the IZATT surname was Sir Walter Izatt (c. 1580-1638), a Scottish merchant and landowner who served as Provost of Perth from 1628 to 1638. He was instrumental in securing the town's charter from King Charles I in 1635.
Another prominent figure with the IZATT name was Alexander Izatt (1759-1805), a Scottish minister and author who wrote several theological works, including "A Treatise on the Nature and Dignity of the Gospel" and "A Sermon on the Death of the Rev. Dr. Erskine."
In the 19th century, James Izatt (1811-1888) was a Scottish-born Australian pastoralist and politician who played a significant role in the development of South Australia's agricultural industry and served as a member of the Legislative Council.
William Izatt (1856-1932) was a Scottish engineer and inventor who patented several innovations in steam engine design and helped establish the Izatt Works in Derby, England, a leading manufacturer of locomotives and other machinery.
Finally, George Izatt (1886-1962) was a Scottish professional golfer who won several prestigious tournaments, including the French Open in 1925 and the Belgian Open in 1928, and represented Great Britain in the Ryder Cup competition.
Demographics
Ancestry and ethnicity for Izatt

The bar chart below shows how Izatt bearers described their own race and ethnicity on the 2020 Census form. 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 Izatt 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.
