Meaning and origin of Rennicks
The surname Rennicks is of English origin, deriving from the Old English words "ræfn" and "wic," which together mean "raven dwelling" or "raven farm." This name likely originated in the early medieval period, between the 5th and 11th centuries, when Old English was still spoken in parts of England.
One of the earliest recorded instances of the name Rennicks can be found in the Domesday Book of 1086, which was a comprehensive survey of landholdings and properties commissioned by William the Conqueror. The entry mentions a certain "Rennic" who held land in the county of Yorkshire.
In the 13th century, the name appeared in various forms, such as "Rennyk," "Rennyck," and "Rennycke," suggesting regional variations in spelling and pronunciation. During this time, the name was primarily concentrated in the northern counties of England, particularly Yorkshire and Northumberland.
One notable individual bearing the Rennicks surname was Sir John Rennicks (c. 1450-1518), a wealthy landowner and member of the gentry in Northumberland. He was known for his involvement in local affairs and his support for the House of Lancaster during the Wars of the Roses.
Another prominent figure was Elizabeth Rennicks (1596-1670), who was born in Yorkshire and later immigrated to the Massachusetts Bay Colony in the early 17th century. She is recognized as one of the first settlers in the town of Salem and played a significant role in the establishment of the local community.
In the 18th century, the name Rennicks was associated with several places in England, such as Rennicks Fell in Cumbria, which was derived from the Old Norse word "fell" meaning "hill" or "mountain." This suggests a connection between the surname and specific geographical locations.
One noteworthy individual from this period was William Rennicks (1721-1801), a successful merchant and trader who was based in Bristol, England. He was involved in the transatlantic trade and played a role in the economic development of the city during the 18th century.

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