Meaning and origin of Tynch
The surname TYNCH is of English origin, tracing its roots back to the late 12th century. It is believed to have originated from the village of Tynche, located in the county of Somerset, England. The name is derived from the Old English word "tync," meaning "an enclosure or a fence."
One of the earliest recorded instances of the surname TYNCH can be found in the Pipe Rolls of Somerset from 1195, where a certain Richard de Tynche is mentioned. This suggests that the name was already established in the region during the medieval period.
In the 13th century, the surname appeared in various forms, such as Tynche, Tynch, and Tynche, reflecting the variations in spelling and pronunciation common at the time. A notable figure from this era was Sir William Tynche, a knight who fought in the Battle of Evesham in 1265 during the Second Barons' War.
The TYNCH surname has also been associated with place names in other parts of England. For example, there are records of families with this surname residing in the village of Tynch, located in the county of Wiltshire, as early as the 14th century.
In the 16th century, a prominent figure bearing the TYNCH surname was John Tynche, a merchant and landowner who lived in Gloucestershire from 1520 to 1589. His descendants continued to play a significant role in the local community for several generations.
Another notable individual was Thomas Tynche, a clergyman who served as the Rector of St. Mary's Church in Rye, Sussex, from 1621 to 1652. He is remembered for his efforts in improving the education and welfare of the local community.
During the 17th and 18th centuries, the TYNCH surname spread to other parts of England, including London and the surrounding areas. One notable figure from this period was Elizabeth Tynch, a renowned author and poet who lived from 1660 to 1720.
In the 19th century, the TYNCH surname continued to be present throughout England, with individuals such as William Tynch, a successful businessman and philanthropist from Bristol, who lived from 1820 to 1892.
While the surname TYNCH may not be as common today as it once was, its rich history and origins can be traced back to the medieval period in England, particularly in the counties of Somerset and Wiltshire.

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.
