Origin
The surname Loosemore is believed to have originated in England during the late medieval period, with the earliest known records dating back to the 13th century. It is thought to be a locational name derived from a place called Loosemere, which likely referred to a marshy or boggy area with loose, muddy ground.
One of the earliest documented references to the name can be found in the Subsidy Rolls of Somersetshire from 1327, which mentions a William de Losemere. This suggests the name may have originated in the Somerset region of southwestern England, where such place names were common due to the area's marshy terrain.
In the 15th century, the surname appears in various records with different spellings, such as Losmore, Losemore, and Losmere, reflecting the variations in pronunciation and spelling common at the time. One notable bearer of the name was John Losmere, who was mentioned in the Court Rolls of the Manor of Wakefield in Yorkshire in 1459.
The Loosemore surname also has connections to the county of Devon, where it is believed to have been associated with several prominent families. One of the earliest recorded bearers from this region was William Loosemore, born in the late 16th century in the parish of Buckland Monachorum.
Another notable figure was John Loosemore, a renowned clockmaker and mathematician born in Exeter, Devon, in 1616. He is credited with designing and constructing several intricate clocks and timepieces, including one that was gifted to King Charles II in 1675.
During the 17th century, the surname continued to be found in various parts of England, with records showing bearers in Gloucestershire, Wiltshire, and other counties. One prominent individual was Francis Loosemore, a clergyman born in Wiltshire in 1648, who served as the rector of several parishes in the region.
In the 18th century, the Loosemore name appeared in Cornwall, with several families residing in the parish of St. Minver. One notable bearer was William Loosemore, born in 1723, who worked as a prosperous merchant and landowner in the area.
Over the centuries, the Loosemore surname has been carried by individuals from various walks of life, including clergy, merchants, artisans, and landowners. While not as widely prevalent as some other English surnames, it has maintained a presence in various regions of the country, reflecting its longstanding historical roots.
Demographics

The bar chart below shows how Loosemore 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 Loosemore surname at the time of the 2020 Census, not any inherent property of the name itself.
