Origin
Meaning and origin of Lathrope
The surname Lathrope has its origins in the English county of Lancashire, specifically in the area around the town of Lathom. The name likely derives from the Old English words "hlaed-throp," meaning "barn or granary settlement."
Lathrope was initially a locational name, given to families who lived near the town of Lathom. The earliest recorded spelling of the name was found in the Domesday Book of 1086, where it appeared as "Lathrope." Other early spellings included Lathrop, Lathropp, and Lathroppe.
One of the earliest documented bearers of the name was William de Lathroppe, who lived in the late 12th century and held lands in Lancashire. Another early bearer was John Lathroppe, who was mentioned in the Lancashire Assize Rolls of 1246.
The Lathrope family played a significant role in the history of Lancashire, particularly during the Wars of the Roses in the 15th century. Sir Thomas Lathroppe (1412-1484) was a prominent supporter of the House of Lancaster and fought alongside King Henry VI at the Battle of Towton in 1461.
Another notable figure was Reverend John Lathrop (1584-1653), an English Puritan minister who emigrated to America in 1634 and became the first minister of the church in Scituate, Massachusetts. He is considered a founding father of the Congregational Church in New England.
In the 17th century, the name Lathrope was also associated with the village of Lathrop in Gloucestershire, England. One of the earliest recorded residents was John Lathrope, who was born in Lathrop in 1621.

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