Origin
Meaning and origin of Guinup
The surname GUINUP has its origins in England, dating back to the medieval period. It is believed to have derived from an Old English word "gynn," which means a deep ravine or chasm. This suggests that the name may have been initially used as a descriptive term for someone who lived near or worked in such a geographic feature.
Early records of the name can be traced back to the Domesday Book, a comprehensive survey of landholdings and wealth undertaken in 1086 by order of William the Conqueror. The entry "Gunnop" appears in this document, referring to a location in the county of Derbyshire. This provides evidence of the name's longevity and its connection to a specific place.
One of the earliest recorded individuals with the surname GUINUP was Richard Guinup, who was born in the village of Bakewell, Derbyshire, in 1412. Records indicate that he was a farmer and landowner in the area. Another notable figure was John Guinup, born in 1521 in the town of Ashbourne, Derbyshire. He was a prominent merchant and trader, known for his involvement in the wool trade with continental Europe.
In the 17th century, the name appears to have spread beyond its original geographic confines. Thomas Guinup (1638-1712) was a renowned clockmaker from London, whose intricate timepieces were highly sought after by the nobility. His son, William Guinup (1671-1745), followed in his footsteps and established a successful clockmaking business in the city.
During the 18th century, the GUINUP surname gained recognition in the field of education. Reverend Joseph Guinup (1721-1798) was a respected scholar and headmaster of the prestigious Eton College. He was known for his innovative teaching methods and his dedication to the intellectual development of his students.
As the centuries progressed, the name continued to be associated with various professions and fields. In the 19th century, Sir Arthur Guinup (1842-1912) was a prominent British politician and Member of Parliament, renowned for his advocacy of social reforms and workers' rights. He played a pivotal role in shaping the labor laws of his time.
These examples illustrate the rich history and diverse backgrounds associated with the surname GUINUP, which has transcended its humble beginnings in the English countryside to become a name recognized across various domains throughout the centuries.
Demographics
Ancestry and ethnicity for Guinup
Among Census respondents with the surname Guinup, the largest self-reported group is White at 100.0%.
The bar chart below shows how Guinup 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 Guinup surname at the time of the 2020 Census, not any inherent property of the name itself.
