Origin
Meaning and origin of Mathwich
The surname Mathwich is believed to have originated in England during the medieval period, with roots tracing back to the Anglo-Saxon era. It is thought to be derived from the Old English words "mæth" meaning "meadow" and "wic" meaning "dwelling" or "village," suggesting a connection to a settlement located near a meadow or grassland.
One of the earliest recorded instances of the name can be found in the Domesday Book, a comprehensive survey of landholdings in England commissioned by William the Conqueror in 1086. The entry mentions a landowner named Mathwic holding a manor in the county of Shropshire.
During the 13th century, the name appeared in various historical documents with slight variations in spelling, such as Mathewych, Mathwych, and Mathewich. These variations were common due to the lack of standardized spelling conventions at the time.
The earliest known bearer of the surname was Sir John Mathwich, a knight who lived during the reign of King Edward I (1272-1307). He was a prominent figure in the county of Warwickshire and held lands in the village of Mathwich, which is believed to have taken its name from the family.
Another notable individual was William Mathwich (1415-1487), a merchant and landowner from the town of Stratford-upon-Avon. He was a contemporary of William Shakespeare and is believed to have been acquainted with the playwright's family.
In the 16th century, the Mathwich family established themselves in the county of Gloucestershire, where they owned several estates and played an active role in local affairs. One member, Thomas Mathwich (1542-1612), served as a magistrate and was known for his contributions to the local community.
During the English Civil War (1642-1651), Captain Robert Mathwich (1610-1678) fought on the Parliamentarian side and was commended for his bravery in battles against the Royalists. His actions earned him a reputation as a skilled military leader.
In the 18th century, the name Mathwich was also found in the county of Oxfordshire, where a prominent family of landowners and scholars resided. Notable among them was Reverend James Mathwich (1725-1802), a respected clergyman and author of several theological works.
Throughout its history, the surname Mathwich has maintained a strong presence in various regions of England, with branches of the family settling in different counties and contributing to local communities in various capacities.

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

Does the Census include every surname?
