Origin
Meaning and origin of Trook
The surname Trook is of English origin, dating back to the 13th century. It is believed to have derived from the Old English word "troc," which means a small settlement or a hamlet. The name is thought to have originated in the counties of Gloucestershire, Worcestershire, and Herefordshire in the West Midlands region of England.
One of the earliest recorded instances of the name Trook can be found in the Subsidy Rolls of Worcestershire from 1275, where it appears as "Trocc." This suggests that the name was already well-established in the area at that time.
In the 14th century, the name was often spelled as "Trok" or "Troke," as seen in various medieval records and documents. It is possible that the name was originally a topographic surname, referring to someone who lived in a small village or hamlet.
During the 16th century, the spelling of the name began to evolve, and variations such as "Trook" and "Trooke" became more common. One notable individual from this period was John Trook, a yeoman farmer from Gloucestershire who was mentioned in the Lay Subsidy Rolls of 1523.
In the 17th century, the name Trook appeared in parish records across the West Midlands region. One interesting entry is from the parish registers of Westbury-on-Trym in Gloucestershire, which recorded the baptism of Elizabeth Trook in 1642.
The 18th century saw the name Trook spread beyond the West Midlands, with records showing individuals bearing the name in other parts of England. One notable figure was Samuel Trook (1737-1811), a renowned mathematician and astronomer from Gloucestershire, who made significant contributions to the field of celestial mechanics.
The 19th century brought forth several individuals with the surname Trook who achieved notable accomplishments. Among them was William Trook (1829-1901), a prominent architect from Worcestershire who designed several iconic buildings in the region, including the Malvern Town Hall and the Malvern Library.
Another prominent Trook from this era was Emily Trook (1848-1923), a pioneering educator and women's rights activist from Gloucestershire. She founded one of the first girls' schools in the area and was a vocal advocate for women's suffrage and education reform.

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