Origin
Meaning and origin of Cashman
The surname Cashman is of Irish origin, with the earliest known records dating back to the 16th century. It is thought to have derived from the Irish Gaelic words "cas" meaning "twisted" or "crooked" and "mann" meaning "man", likely referring to a physical characteristic or occupation of the original bearer.
In some old Irish manuscripts, variations of the name such as Casmain, Cassmain, and Cassmane can be found. These early spellings suggest that the name may have originated in the counties of Cork, Kerry, or Limerick, where Irish Gaelic was widely spoken.
One of the earliest recorded instances of the name appears in the Fiants of the Reign of Elizabeth I, a collection of legal documents from the 16th century, where a "Donill Cassman" is mentioned in a land grant in County Cork in 1586.
The Cashman surname is also found in the Petty Census of 1659, which was a survey of households in Ireland conducted during the Cromwellian period. This record includes several Cashman families living in the parishes of Killeagh and Kinsale in County Cork.
Notable individuals with the surname Cashman throughout history include:
1. Timothy Cashman (1866-1942), an Irish-American businessman and politician who served as a member of the Massachusetts House of Representatives.
2. Patrick Cashman (1862-1938), an Irish-born prelate who served as the Bishop of Ossory from 1913 to 1938.
3. John Cashman (1835-1911), an Irish-born merchant and politician who served as the Mayor of San Francisco from 1888 to 1890.
4. Bridget Cashman (1860-1928), an Irish-American labor activist and leader in the Women's Trade Union League in the early 20th century.
5. Daniel Cashman (1776-1842), an Irish-born explorer and trader who was one of the first European settlers in what is now Western Australia.
While the Cashman name has its roots in Ireland, it has since spread to various parts of the world through emigration and is now found in countries such as the United States, Australia, and New Zealand.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
