Meaning and origin of Fitzsimonds
The surname Fitzsimonds is of Anglo-Norman origin, deriving from the prefix "fitz", meaning "son of", and the given name Simonds or Simond. It originated in England after the Norman Conquest of 1066, when many Norman families began using patronymic surnames to denote their lineage.
Fitzsimonds is thought to have arisen in the 12th or 13th century, with some of the earliest recorded instances found in medieval records from counties like Gloucestershire and Oxfordshire. The name was initially spelled in various ways, such as Fitzsimond, Fitzsimons, and Fitzsymonds.
One of the earliest known bearers of the name was Roger Fitzsimonds, who was mentioned in the Pipe Rolls of Gloucestershire in 1200. Another early record is that of William Fitzsimonds, who was listed in the Hundred Rolls of Oxfordshire in 1273.
The surname Fitzsimonds has been associated with several notable individuals throughout history. One example is Sir John Fitzsimonds (c. 1395-1458), a prominent English landowner and Member of Parliament for Gloucestershire during the Wars of the Roses.
Another notable figure was Richard Fitzsimonds (c. 1510-1572), an English priest and theologian who served as the Dean of Winchester Cathedral during the reign of Queen Elizabeth I.
In the 17th century, Humphrey Fitzsimonds (1624-1694) was a renowned English clergyman and author, best known for his work "The Loyal Subject's Belief" published in 1679.
Moving into the 18th century, William Fitzsimonds (1718-1789) was a successful merchant and landowner in Gloucestershire, where his family had resided for generations.
More recently, James Fitzsimonds (1898-1971) was a British military officer who served in both World War I and World War II, earning the Distinguished Service Order for his bravery in battle.

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

Does the Census include every surname?
