Origin
Meaning and origin of Twohill
The surname TWOHILL is of English origin, originating in the county of Wiltshire, England during the late medieval period. It is derived from the Old English words "twi" meaning two and "hyll" meaning hill, referring to a geographical location with two hills.
The earliest recorded use of the surname TWOHILL dates back to the 13th century, appearing in the Hundredorum Rolls of 1273, a census-like record of landowners and tenants in England. One of the earliest known bearers of the name was William de Twohill, who was listed as a landowner in the village of Twohill, near Warminster in Wiltshire.
In the 14th century, the name TWOHILL was also found in various manorial records and tax rolls across Wiltshire and the neighboring counties of Somerset and Dorset. This suggests that the name was well-established in the region during this time period.
One notable figure in the history of the TWOHILL surname was Sir John Twohill, a military commander who served under King Edward III during the Hundred Years' War. Sir John was born in Twohill, Wiltshire in 1320 and fought in several battles against the French, including the Battle of Crécy in 1346.
Another historical figure was Richard Twohill, a wealthy merchant and landowner from Wiltshire who lived during the 16th century. He was involved in the wool trade and his name appears in various business records and property deeds from the late 1500s.
In the 17th century, the TWOHILL surname began to spread beyond its ancestral home in Wiltshire, with branches of the family settling in other parts of England, as well as in Wales and Scotland. One notable individual from this period was Robert Twohill, a Puritan minister who was born in Twohill, Wiltshire in 1612 and later became a prominent figure in the Massachusetts Bay Colony, serving as a pastor in Boston.
During the 18th and 19th centuries, the TWOHILL surname continued to be found across various regions of the British Isles, with some members of the family emigrating to North America and other parts of the world. One notable individual from this era was William Twohill, a British explorer and naturalist who was born in Somerset in 1792. He traveled extensively throughout Africa and the Middle East, making significant contributions to the study of botany and zoology.

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