Origin
Meaning and origin of Dangar
The surname Dangar has its origins in the English counties of Lancashire and Yorkshire, where it first appeared in the 12th century. It is believed to be derived from the Old English words "dene" meaning a valley, and "gara" or "garra" meaning a triangular piece of land or a strip of land between two streams.
The earliest recorded mention of the name dates back to 1199, when a Roger de Denegare was listed in the records of Lancashire. In the Pipe Rolls of Yorkshire from 1230, a John de Denegar is mentioned, indicating the name's presence in both counties.
During the 13th century, the surname appeared in various spellings, including Denegar, Denegare, and Denghire. These variations reflect the local dialects and the evolution of the English language over time.
One notable early bearer of the name was Sir Thomas Dangar (1444-1518), a wealthy landowner and member of the gentry in Lancashire. He was known for his philanthropic efforts and donated funds for the construction of a chapel in his local parish.
In the 16th century, the surname spread to other parts of England, and records show a Henry Dangar (1528-1592) residing in the county of Dorset, where he worked as a merchant and trader.
The name also found its way to Ireland, possibly through English settlers or through intermarriage. A prominent Irish bearer of the surname was Michael Dangar (1685-1759), a landowner and member of the Irish Parliament who represented the constituency of Wicklow.
In the 18th century, the Dangar family established itself in the colony of New South Wales, Australia. Henry Dangar (1796-1861), a surveyor and explorer, was one of the first to map and survey the region around the Hunter Valley and played a significant role in the early development of the colony.
Another notable Australian bearer of the name was Thomas Dangar (1808-1884), a pastoralist and landowner who established several successful sheep stations in New South Wales and became a prominent figure in the wool industry.
Throughout its history, the surname Dangar has been associated with individuals from various professions, including landowners, merchants, politicians, surveyors, and pastoralists, reflecting the diverse backgrounds and achievements of those who have carried this name.

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

Does the Census include every surname?
