Origin
Meaning and origin of Tyas
The surname Tyas originated in Yorkshire, England in the 13th century. It is believed to be derived from the Old English word 'tyge', meaning a small enclosed field or enclosure. The name was likely initially given as a locational surname to someone who lived near or owned such an enclosure.
Records show the earliest documented spelling of the name as 'de Tyese' in the Yorkshire Poll Tax Rolls of 1379. The Poll Tax Rolls from the same period also list a John de Tyese, indicating this was already an established surname by the late 14th century.
The Tyas name appears in several early English records, including the Subsidy Rolls of Yorkshire in 1572 which mentions a Thomas Tyas. The Lancashire Wills records from 1679 also refer to a Thomas Tias, likely an alternate spelling of the name at that time.
One of the earliest notable bearers of the Tyas surname was John Tyas, born around 1550 in Huddersfield, Yorkshire. He was a prosperous landowner and is recorded as purchasing land in the nearby village of Almondbury in 1587.
Another early Tyas of note was William Tyas, born in 1612 in Kirkheaton, Yorkshire. He was a respected yeoman farmer and left a detailed will upon his death in 1683, providing insight into the family's landholdings at that time.
Moving into the 18th century, the Tyas surname spread slightly beyond its Yorkshire origins. Joshua Tyas, born in 1724 in Halifax, Yorkshire, was a successful merchant who later relocated to London where he established a prominent trading business.
The 19th century saw several accomplished individuals bearing the Tyas name. Reverend Thomas Tyas, born in 1809 in Huddersfield, was an esteemed clergyman who served as the vicar of Mirfield in Yorkshire for over 40 years until his death in 1891.
Another notable 19th century figure was Edmond Tyas Cook, born in 1828 in Yorkshire. He was a renowned editor and writer, serving as the editor of the Pall Mall Gazette newspaper in London from 1865 to 1892. He published several influential works during his lifetime.
While the Tyas surname originated from a small, localized area of Yorkshire in the Middle Ages, it managed to spread gradually over the following centuries. By the 19th century, bearers of this distinctive English surname could be found in various parts of the country, maintaining its strong ties to its Yorkshire roots.
Demographics
Ancestry and ethnicity for Tyas

The bar chart below shows how Tyas 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 Tyas surname at the time of the 2020 Census, not any inherent property of the name itself.
