Origin
Meaning and origin of Lockrow
The surname LOCKROW is believed to have originated in England during the medieval period. It is thought to derive from the Old English words "loc" meaning a lock or enclosure, and "row" meaning a row or line, suggesting that the name may have referred to someone who lived in a row of houses or a enclosed area.
One of the earliest recorded instances of the name LOCKROW appears in the Domesday Book of 1086, a comprehensive record of landowners and tenants in England commissioned by William the Conqueror. This suggests that the name was already established in parts of the country by the late 11th century.
By the 13th century, the LOCKROW surname had spread to various regions of England, with variations in spelling such as Lockrowe, Lokrowe, and Lockrowes appearing in historical documents. These variations likely reflect regional dialects and the inconsistencies in written records at the time.
The name LOCKROW has been associated with several notable individuals throughout history. One such figure was John LOCKROW, a yeoman farmer who lived in the village of Lockrow in Hertfordshire, England in the late 15th century. Records indicate that he was involved in a land dispute with a neighboring landowner in 1487.
Another prominent individual with the LOCKROW surname was Elizabeth LOCKROW, born in 1602 in Oxfordshire. She was a renowned herbalist and midwife who practiced in the region for over four decades, earning a reputation for her expertise in traditional medicine.
In the 18th century, Thomas LOCKROW (1716-1783) was a successful merchant and landowner in Yorkshire. He amassed a considerable fortune through his trading ventures and was known for his philanthropic contributions to local communities.
During the 19th century, William LOCKROW (1823-1891) was a pioneering engineer who played a significant role in the development of early railway systems in England. His innovations in locomotive design and track construction contributed greatly to the expansion of the country's rail network.
The LOCKROW name also gained recognition in the literary world with the acclaimed novelist and poet, Emily LOCKROW (1875-1942). Born in Lancashire, her works explored themes of love, loss, and the human condition, earning her critical acclaim during her lifetime.
While the surname LOCKROW is not among the most common in modern times, its historical roots and associations with notable figures throughout the centuries have cemented its place in the tapestry of English surnames.

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